One Call Away is already Charlie's next single there and it's already in the top 200 so he'll probably perform that.
She'll be in the UK in 2 weeks to help Rita with the judging thing so the performance is probably by then.
By far the best song on her album. I remember seeing her old YouTube video with her singing it live and playing the ukulele. It was actually this song that made me interested in her when AATB started to gain major attention.
The song did NOT need John Legend though. I wish there was a version without him, his feature just seems so unnecessary.
