I think she did great! people always expect high notes, belts etc. This is due to the fact that people minds have been over stimulated and fail to appreaciate the simplicity of this performance. The subtle and delicate and pure tone which I believe is more appropriate for this setting. Look at the performance overall with the beautiful back singers hormonising.... Look at the totality of it rather than concentrating on Leona ...Leona has a faboulos tone I have to say!

Loved Leona for 15 years. Great singer. Great human being

She's my favourite singer ever

Her voice is very subtle and sophisticated here. I had goosebumps since 1:47

British people should be extremely proud of Leona Lewis. A real artist and a real quality singer and truly a real role model for younger generations. Most of the the other singers nowadays are a bunch of rebels broken souls and attention seekers and complicated individuals who probably did not have the parental and family support this yound lady had.

Spectacular, looking regal and sounds that touch your soul. There is no other like Leona.

Her beauty and sounds of an angel! No one like you SLAYONA! ✨🎄🤍🤍🤍

Precious pure..voice full of reverence.. Beautiful performance Leona ❤️

Such a beautiful angelic voice, no need to compare to the x factor period. Madness to have this kind of voice 🤍

Trenma voz Leona

Much better than other recent lives. Not the best, but I think this is 80% of her prime

She remains the best vocalist on the planet...!

She was great. That end was epic. Love her. She is truly one of the greatest singers in the world. Greetings from Chile. 💜

This video has better quality than the one I watch on TV, kinda eye-catching

She sang it with passion and compassion and humbled herself by glorifying God. She knew she was in the Lord’s house and all glory and honour is for Christ.

She sang beautifully her voice is incredible. I wish she wasn't judged by being perfect all the time after what she's been through with her voice. People don't expect Mariah Carey to sing like her prime years.

Westminster Abbey is not a usual stage. Well done 💕💕💕

Love Leona!!!!💜

Fantastic singer gives me goosebumps ❤️

Beautiful...Perfect pitch and volume output. This is a Christmas song not a rock concert. :)

Amazing it was beautifully sung and she did captivate William and Kates attention and the audience. Her tone is so special and her vibrato.

Simple. Beautiful

Amazing perfomance Leona ❣️

Masterpiece

Breathtaking 😮

Absolutely beautiful 😍

Incredible beautiful of Holy Night after Mariah. I mean the first is Mariah, and the second is Leona and Tori Kelly. What amazing voice on earth. How proud British people to have her. Love from Indonesia 🇲🇨

And in the end, the world will see incredible things that had never seen before. And the world will rememeber that love was, is and will always be the most important thing in the world ❤️🧡💛💚💙💜 God will always care and protect love and good people of the world ✝️✝️✝️✝️✝️✝️ Despite the evilness of the world, Jesus is always by my side ✝️✝️✝️✝️✝️✝️ Thanks God, because despite the evilness, pain and sufferment of the world, you make me a man of top 1% ❤️🧡💛💚💙💜 Happy Merry Christmas to all the good people of the world 🎄🎄🎄🎄🎄🎄🎄 God bless you all ✝️✝️✝️✝️✝️✝️

beautiful performance

Absolutely beautiful!!!!!

beautiful

MY fave Female singer!!!!❤

wow 😍

I can hear that she's holding back because she's still not comfortable belting, but oh my, her tone sounds beautiful. I low-key wish she sang Ave Maria ✨

Beautiful! A beautiful concert!

Love leona she is amazing ❤️

Beautiful 😍

serenity.

I can't believe shes had thyroiditis in her throat n still be able to single. I loved her since her audition on x factor. Im dyin for her to get back to her happy and homeless era. She would be unstoppable again

So beautiful Leona absolutely fantastic

AWESOME LEONA

What an amazing voice😍😍😍

Excellent voice

Will forever love Leona ❤

Perfeito !!

No matter who sings this it is always beautiful. Celine Dion sang it best by far.

Lovely tone

love you so much. we need a new album spirit style

The royals seem memorised by her

#Gorgeous 🥰

❤️❤️❤️❤️❤️

Shaky in parts but one of the best performances she delivered lately, if not the best one.

Not at her best because she was on tour with Gary, but much better than I thought

She was controlled because the venue demands it ..very respectfully and beautiful song and voice

😍😍😍😍

Underrated.

Beautiful, just wish she had sung the other verses.

She gave it a go bless her 🙈if you don't compare it to anything else then it was ......ok 👍😀

Beautiful wasn’t really the setting for a full on belt anyway gorgeous what she did with it

just sang a song?

Started off very shaky but she made up for it as the song went on.

This was good, that’s about it… she used to be sensational. She sounds like a shell of herself

The backing singers have far more to offer vocally!

omg what happenned to her voice :-( She should have playback on some parts

why is her voice so unstable?

Only Mariah Carey nice voice

No belts ? No head voice ? No whistles ? Oh Leona. Where have you gone ?

Vocally it was ok. However it was very boring. Maybe she had a cold and was playing it safe.

Didn't know she'd had a nose job, pity, she looked fine before

Years and years of bad technique gets you a weak, underdeveloped tone. All head, no full, zero chest. Breath control is all over the place. But she’s pretty, I guess.

I wonder what happened to her voice? She has no power and no real tone to it anymore
