Oasis Jeff, you are baaaad.
How about "I don't know how to love him" from JCS? That COULD work. Then there's "Gay Paree," wherever that came from. "What do the simple folk do?," from "Camelot," has a line about life's being "merry and gay," followed by "Hear Venus call, come one and all, and taste delight while you may." (That sure meant something different when I first heard it

). And how could I forget "You're a queer one, Julie Jordan?"
Almost any love song would work, as long it's in a singable key for a man and it doesn't wax romantic about his love interest's femininity. I'd definitely stay away from "I Am Woman, Hear me Roar." I think "Music of the Night" would work if you can sing it -- goodness knows that I can't, although some women can pull it off.
I guess the choice will come down to whether you're aiming for campy or serious -- personally, I like camp.
