“I was asked to work on the soundtrack, but I said, ‘I’d like to do it with Mick Jagger.’ I thought that Mick and I could write stuff that really related to the character of Alfie, and I thought that keeping the soundtrack kind of rootsy, bluesy, with a ‘60s feel would be better than an epic score.

“There’s some great songs on it, like The Blind Leading The Blind, Old Habits Die Hard. We had a lot of fun doing it. We had a script and the rough cut of the film, and we worked very closely with the director [Charles Shyer]. It was very interesting.
