The hit maker dedicated the song on what would have been the late star’s 33rd birthday on Wednesday evening.
Adele talked about Amy on the stage and called her a “genius” and the artist who inspired her to write her own songs before performing an emotional rendition of the ballad.
Talking to fans she said:
‘I feel like I owe so much of my career to her. Her first album Frank, that album really changed my life. I used to think she’s the coolest motherf***er.
‘Because of her I write my own songs, if it wasn’t for her I wouldn’t be happening. I’m also completely happy with all of the music that she left behind because it’s genius, but every day I wish I could hear a new song from her.
