She's an incredible vocalist, that's my favorite guest performance ever!

it's mine as well! she was so good

I agree, incredible!

Sounded quite a bit like Kitty in some places, and like how Janet wishes she sounded in others lol

That was incredible!

Totally showed everyone how you do it!

It was remarkable. Mind Florence is the best artist to ever grace that stage so it's hardly a shock!

i honestly dont think she sounds like kitty because kitty sings through her nose.. however i completely agree about janet

It was incredible, i was completely blown away! Mind you i'm a massive fan so i'm biased! haha

Bloody fab

Love the performance but just wish it was a different song. Never Let Me Go or Heartlines maybe ( I like Shake it out, but its been out for a while, nice to see another song).

Now that's how you sing live!

I thought she was amazing too.

incredible loved every second

Great voice, performance and staging.
