Amy Winehouse steps out to perform 'Valerie' with Mark Ronson's new band.
Ronson debuted his new band at jazz café the 100 Club in London last night, playing some tunes from his album Version.
One song, 'Valerie', actually saw the original collaborator Amy Winehouse step up on stage for a very rare performance.
Footage shot shows a very spindly Winehouse slowly staggering around the stage and mostly sing-talking her way through the song.
Winehouse and Ronson have recently collaborated on a song for a forthcoming Quincy Jones tribute album, and Island have claimed that she will have a new album out before the end of 2010.
Have a look at her performance below.
