I can't remember this comedian's name. Help me?

A few years ago, I saw a comedian who sat at a piano, one of the original songs he sung was titled something like ' I'd do anyone but you' and it was about how a woman would have sex with everybody else apart from him. I want to listen to it again, but I can for the life of me, remember his name. Does anyone here have an idea? I know it's not much to go on but if anyone knows, then it's the fine folk here.
Thanks

James Sherwood, here's the song :
