Well, maybe this is just ridiculous and forgive me if it is, as this prayer request isn't nearly as important as for the many Orthodox out there, but I figured why shouldn't I give it a go?
David Gilmour, the lead guitarist of Pink Floyd, said in his latest interview something to the extent of: "I'm an atheist. But I would prefer if I was of faith. In my early years I tried to force myself to believe but I just couldn't do it." He goes on to explain how he is terrified of his forthcoming mortality, how he is having such a hard time dealing with it even though he is not facing a deadly sickness of any kind right now. To me this shows that this man is in some way searching for God, he just doesn't know where to go. Too bad we can't tell him where!
I've always liked Dave Gilmour. He seems like a decently modest fellow in comparison with other rock musicians. His lyrics were never anti-Christian in my view (he hardly writes his own, btw). Maybe if we say a prayer for him you never know, he might just bump into Bp. Kallistos Ware ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€š as both live in England
There's no reason why a celebrity like him could not be affected by our prayers, and I'm sure there are many Orthodox who have enjoyed his music and been touched by it.
