I just came across this one. It's a cover, but read what Donal Gallagher says about it, and The Commitments.
"Roddy Doyle, who wrote that, based it on Rory. Rory was a sort of muse for that – kind of the guy who didn’t want to play this show band music, and went out and sort of went for a different form of music, i.e. the blues. In the movie, it’s soul music. In fact, when they were casting for the movie, [director] Alan Parker called the office. He had gone back to the writer, Roddy Doyle, and said that they couldn’t find the trumpet player, Lips or whatever the guy was called. Roddy said to Alan Parker “Well, if you can’t find him, truth be known, I wrote it about a guitar player – Rory Gallagher. If you could get Rory to play the part of Joey ‘Lips’, the trumpet player, I’ll rewrite the screenplay to be a guitar player. The whole legend of ‘did he play with so-and-so’, that all comes from Rory – did Rory play with Muddy Waters, did he play with Jerry Lee Lewis, did he have this reputation, did he really go out there and do it?” I managed to get Rory as far as Alan Parker’s office, and Rory just refused. He did a reading for him, but just said “Look, I’m not the one.” At the time, I was praying that he’d take the part. I really thought it would be a life-changing experience for Rory at a crucial point in his life. I thought he’d really have to look at life differently. It wasn’t to be. But in fact, in the movie, the last line is “Let’s go back to Gallagher’s.” -- Donal Gallagher
