He's a gay stand-up/performance artist who (I think) hails from Manchester. I've only seen one of his shows - interviewing members of the public in a fairly straight (ho ho) way about various mundanities, accompanied by his frighteningly attired mute sidekick, whose name I can't remember. I found it all rather unsettling. Particularly the sidekick.

was he the one on that piss-poor sketch show - comedy nation?

No, that was Irish stand-up Michael Redmond, I think.

He was on Comedy Nation. He was shit. As parodied in the last SOTCAA fringe guide:
something like "... thinks being gay means that he doesn't need to think of a proper act". Basically, he'd walk on, deliver some line he thought would _epater les breeders_, then that would be the end of the sketch.
It was somewhat unsettling, but not funny. As I remember it, it would normally be some sort of quasi-Nietzschian shit. Imagine a sort of high-camp League Against Tedium.
The "Fast Show"-inspired tendency to very short (often one-line) sketches is something that I can't stand. It worked on the Fast Show, but it's often an excuse for laziness.
