The super-producer played guitar on ‘Valerie’, the song which he made famous when his Amy Winehouse-fronted version was a massive hit in 2007.
In a nod to the cover, the band’s frontman Dave McCabe said: “Does anyone know Amy Winehouse?”
The crowd responded with a cheer and McCabe replied: “And guesting on this song, the person who actually made this song what it is, Mark Ronson.”
Ronson then came on stage, wearing a grey suit and hat, to play guitar on the song.
When the song finished and Ronson exited the stage, McCabe said to the cheering throng: “Let’s hear it for Mark Ronson – he’s already done his gig, he didn’t need to do that”, referring to his earlier Other Stage performance.
