Who else is blown away by Kat's VOCALS and COMEDY these last few days? SO. MUCH. TALENT.

I love how she was playing around, but also slaying vocals lol

I'm an American nurse working in Italy in a field hospital for Covid patients, and I NEEDED THIS song and a laugh or five today. Thank you so much.

It's amazing how she can be so goofy and serious at the same time while singing like that! Great Celine impression too. The more I see of them together the more I love them.

Really enjoyed this version. Part slapstick, part seriousness, all heart. Thanks guys.

Kathrine's voice has taken on a whole new dimension

The wholesomeness when he goes “woo!” And closes his eyes. My heart can’t take it 😭

Love the way David glances at her adoringly when she nailed those high notes!

It's a joy to watch and listen to the two of you having so much fun! What a voice!! David you have met your match!!

#McPheeeandFoster I really can see their sincere admiration and love for each other, but what is most amazing is their lightheadedness and ability to be their authentic selves.

She can sing; he can play. Both are sooooo talented! They have been blessed with such talent.

If I could sing like that I’d never just speak words again...🕊

Dang Kat! That is scary good...l mean, there’s only a handful of singers in the world who can just stand at piano without any post mix and sound like that. What a talent! Nice job!

Beautiful voice! Thanks Katherine for your humor. David is a lucky man. You both are lucky to have each other.

Holy crap how could you think this would flop. It is incredible. Kat does it (like everthing) amazingly

Her belt has improved dramatically since her Idol days. She must have had a great voice teacher that taught her how to open up her voice and really project on those big notes, because they sound so much more sturdy and well-supported now.

David getting excited by Kat's vocals, like right there with ya buddy, every time lol!

The "near, far" at 2:54... 😂😂😂 She slayed the Eb5s at 3:47 at 4:02! 😍 So amazing to hear the growth in her voice in the fifth octave since she was on Idol.

Kat is so damn funny 😂 honestly was laughing out loud, when I watched the livestream 😁 all the props and her 'acting', while still sounding amazing!

Kate, you have the wit and humor of Celine and the voice of a angel. You make a beautiful couple. Celine was funny like this with her late husband. Keep making us laugh. Love you both!

I love when he says: How about your voice?

I really needed to see this today. Your voice, your humour and the chemistry between you two is amazing. Sending the biggest warmest hugs from Dublin in these dark times ❤️

The voice is spot on, the comedic bits take it to a new level!

Wow, you really are helping the time go by with this Coronavirus. You two are awesome. David, the songs you have written and your voice is awesome. Kat, your voice is a voice second to none. You are amazing!! I want to see the two of you in the Phoenix area.

he found his muse. this is so adorable

That drawing!! I literally LOL’ed!! Amazinggggggg voice, Kat. Always loved your voice so much. So clean and crisp. David’s piano is amazing too!

I was cracking up. It is so nice to see two amazingly talented people sharing what they have in a very real, down to earth way. Kudos to them for taking time to make a KZfaq channel to be fun, silly, serious and lovely all at the same time!
