While he has yet to start on a follow- up to 2010’ s Record Collection, Ronson’s been busy in the studio. He has several songs on the new Bruno Mars album.
‘‘ I’m not allowed to talk about it,’’ he says. ‘‘ But it’s incredible.’’

Rumours suggest next year’s Future Music Festival will be headlined by the Stone Roses, one of his favourite bands.
‘‘ If that’s true I will so be on that bill,’’ he says.
