‘I still don’t know what to say about it,’ Gavin tells U2.com’s interviewer, then proceeds to talk about his 50th birthday celebration at Carnegie Hall for quite a bit:

Question: What have Laurie Anderson, Andrea Corr, Courtney Love, Lydia Lunch, Maria McKee, Shane MacGowan and Rufus Wainwright got in common with Larry, Bono, Edge and Adam. Answer: They’re all fans of Gavin Friday and they’re all taking part in a one-of-a-kind show in New York next week, set to raise funds to combat AIDS in the poorest countries.

An Evening with Gavin Friday and Friends, on Sunday October 4th at Carnegie Hall in New York, is curated and produced by Hal Willner, someone with an unrivalled track record in one-off musical events inspired by maverick artists from Leonard Cohen to Kurt Weill, Tim Buckley to Thelonius Monk.

Gavin, of course, has been hanging out with the members of U2 since before they were the members of U2 and is invariably to be found with them in the studio when an album needs to be finished… or out on the road, when a tour is about to kick off. Right now, he’s working on songs for his own next solo album due in 2010. We caught up with him in Dublin to find out more about the Carnegie Hall show:

“Believe it or not, this was not born in my head. I think I was on some kind of TV show, maybe 12 years ago, and I was asked about my musical ambition and I said I’d love to play Carnegie Hall before I’m 50. That was the seed of all this. Then earlier this year a gang of us went away for a day to celebrate the 50th birthday of Guggi and at the party, Bono, who turns 50 himself next May, said to me, ‘Do you know what you’re doing for your fiftieth ?’ I said I didn’t have a clue and that I’ll probably run away to avoid the attention. He said he did know what I was doing, that I was playing Carnegie Hall.”
