Simone covered This is Halloween. Floor Jansen covered Let It Go on Nov 14th. I think Simone and Floor need to cover a song together!

I've always loved Simone's vocals and i've been aware of Oliver's talent, but i didn't know he is THAT talented. He nailed the voices and the expressions.

I loved it. Family united in an excellent performance, I loved Vincent participating too. Happy Halloween! 🎃

Me encanta......Gracias Simone, un abrazo desde Bogotá - Colombia❤️

Why am I seeing this only NOW???? This is soooo good! And so fun! I love that little Vincent also participates

Oliver un campeón y Simone la mujer más hermosa del universo.Un trabajo maravilloso han hecho.Por más música juntos.

Dear Simone, from the deepest part of my heart let me tell you that me as a fan would be the happiest if videos and colaborations like this were more frequently 😍😍😍 I'm in love with this 🖤🖤🖤

Dear Simone and Oliver thank you for this amazing song! My daughter 16 months old knows this song since her first 3 months! She dances with it, she relaxes and goes to sleep in the night! Oliver, you are a great musician and Simone, your voice is devine! One day i will bring her with VIP ticket to meet you both! Best regards from Poland!!❤

Simone, Oliver and Vincent as well, this is breathtaking! I smiled through all the song. An amazing surprise and interpretation! 😍

Would love to hear Simone cover Sally's Song. Amy Lee did a great version a while ago too.

OH ! Simone Simons covering This Is Halloween ? That's AWESOME !!! :D :D

What a BEAUTIFUL surprise!!! Also awesome to have you on youtube again! ❤️

What a wonderfull surprise! Simone, Oliver and Vincent having fun together. Love this cover, and love you all! Greetings from Mexico!

This version is very EPICA ... I loved you Simone Simons you are my favorite female vocalist

The Queen nailed it again. Beautiful and joyful, the funny voices made me smile to no ends 🖤

This makes 2020 better! Thank you Simone, Oliver and of course Vincent! Greetings from Hungary! 🇭🇺

This is so lovely! All the different voices, and the Vincent part😍

Such a great spirit and fun coming from this cover! And I totally dig all the voices! 😍

Incredible and beautiful the own style that they put to the song. How is it possible that everything Simone and her family does is always right? perfection taken to another level

No me canso de escuchar este tema, lo amooo, me pone feliz ver a la familia completa... Saludos desde Argentina

This is my favourite version of "This Is Halloween." It's beautifully arranged and creative. Simone's voice is absolutely beautiful and the funny voices are joyful and they made me smile! ♥️

This is so beautiful. I’ve never heard Oliver singing, he’s good. They make such a wonderful couple.

Tudo o que eu precisava! Uma música que eu adoro, de um filme que curto demais, cantada pela talentosa e genial Simone Simons!

Amazing cover from great musicians, Simone's voice is without doubt one of the most beautiful voices I've ever heard it always mesmerize me. 🎃👻💜

OMG! The best cover forever, Happy Halloween Simone, Oliver and Vincent! 🎃🎃

Turns out Simone would have been a very good fit on Nightwish's album "Imaginaerum".

Congratulations! It's everything this halloween needed! You guys are the sweetest thing, much love!

What a family. Can't love this more. Heart full of admiration 😍

I like it so much!! One of my favourite films and my childs too... I saw Simone singing some parts in a Halloween night concert with Epica... I gave her a Sally key chain last year in Paris meet and greet... Love this cover!!!

Everything with that beautiful voice of simone simons it's amazing!

Anything sounds just perfect when Simone's the one singing ❤

I *SOOO* wish you could release this as a single, I absolutely love this rendition.

I watched this movie when I was a kid in VHS and it is still one of my favorites movies. My niece that is coming will sure know how to sing the songs. At least, I hope so! The version that you both sing is fantastic. A special way to begin the day with right foot. So, Thank you!

It’s been almost 2 years and it is still awsome as hell. Love it 🎃

Beautiful! Jus beautiful; now I want this version in the movie 🤭🤭

The fact that you guys clearly had the time of your life doing this cover makes it a thousand times more enjoyable. Thanks and a very Metal Christmas!

It's been almost 5 months after, and I still can't stop listening to it. Great voice, even the other voices you make. Marvelous voice

Wow! I’ve never heard you do those kind of “character voices” before!

Love this, Happy Halloween! 🎃👻

Wow. Very good cover Simone! I love the fact you guys didn't change the original melody, which is what makes this song so special. Top-notch cover!! Loved it!

This is perfection! Thank you so much for sharing this with all of us. So much fun! What a wonderful treat!

Another year later and still by far my favorite Halloween song!

I LOVED this cover! This is one of my favorite movies and you are one of my favorite female voices. This is amazing!

I was one of those odd 90's kids who never cared much for The Nightmare Before Christmas-anything. Until now. 😍🖤 Thank you Simone and Oliver!

This is so lovely and fun! Hope to see more of these! ❤

I really hope you'll stick around for long on youtube! 🖤 So glad to see this amazing cover, I always regretted that I've missed seeing it live in Krakow 5 years ago :)

I love this song, and now that you are singing it i love it even better, i always love to hear your music from epica and other projects, simone you are simply AMAZING, so much love to you and your beautiful family❤️❤️

What a beautiful surprise 🖤🧡🖤 thank you, guys! And Vincent of course :)

Para mi el mejor cover, geniales y hermosas voces de Simone y Oliver, sin duda tienen un montón de química y son un gran dúo 💖💖👍

this is so fantastic!great family singing together.Great Job.congrats to you all.i enjoyed seeing and hearing you singing this song.

Best of the best❤love it from the begining to the end,flawless and the best cover i've ever heard

Wooooooooow. My favorite version so far. Such a talented family, i loved Vincent's costume. Happy Halloween 🎃

This is one of the funniest covers I've ever seen. Simone's voice shifting, that one moment where Oliver's looking at the songbook like 'what is this note' and the guest star. I don't know how they did it without anyone bursting into laughter. It's amazing, and it's fun to see Simone having fun.

I just can't believe this, absolutely amazing the three of you!

THIS IS AMAZING!! BEST HALLOWEEN TREAT! Thanks, Simone!

Oh my gosh, I had no idea Oliver could do awesome character voices. Obviously a man of so many undiscovered talents 😊. I can see how much fun he and Simone are having and I really hope you both do more cool collaborations.

Es una gran y sorprendente versión , I love their songs and their all music. 🎃👻

I need the whole movie sung by you all. Masterpiece.

i found it very very sweet to see the whole family performing!

Awwww!! Such a lovely video, i love to see all your family working with you

Wowww!! It's so spooky and fun!! And I loved this mix of voices - amazing!! From now, we gonna turn on this song officially like our Halloween anthem. Thank you!! I loved it!! 🎃 🎃

THIS IS PERFECT! What a lovely family

Oh wow... I've wanted to hear this so much in studio version after I heard this live on YT! Perfect is not enough to say :D

I loooove this beautiful cover, congratulations simone,oliver and vincent💕💕💕

Oliver made an amazing interpretation 😍😍😍 Simone amazing as always ❤️

I fell in love with the cover. Beautiful. @Simone, your son is just like you!

How did I not see this until now? My Friday just became a little better. Loved how much fun you guys seemed to have had while making this.

Amazingly well done and very pleasing to the ears. Keep up the good work, milady.

Woooooooow! This is amazing!!!!!! You guys did an amazing job! ❤️👏🏻

A wonderful surprise! Now I'm dreaming of you singing This is Hallowren followed by Amy Lee's version of Sally's Song

So much talent in one wonderful family! 💛

2:00 my favorite moment 😂 Simone Simons can definitely sing everything !

The whole movie characters sung by only two people with insane vocal talents 💗🎃

Isso simplesmente salvou meu dia!!! ❤️

This is so enjoyable, perfect combination of quirky and creepy 💜🎃

Now I have a favorite version of this :D This is so fun to listen to and watch! 🎃🖤

This was so much fun even if I'm late to the video. Great job!

Never heard Oliver sings, really impressed! Best musical family ❤️

So this is the surprise Simone talked about on the interview yesterday! I love it! Amazing ❤️

Thx for this amazing halloween surprise, have an awesome spooky night at home 👻🎃🤘🏻

The best Halloween performance I've ever seen.

This is absolutely AMAZING! Please put this on an album!!!

I love it!!! Best treat for this halloween night!!!

I wonder how many times Vincent has told "My father is from Camelot (Kamelot)" and "My mother is epic (Epica)" jokes to his friends.

Excelente versión 🤘🏻🎃 🇨🇴 Halloween 2021
