That Andrew WK was a confection, surely, isn't that surprising? In perhaps the first interesting appearance he's made, the current WK admits that his character was designed by committee and has been played by more than one actor:
I’m not the guy you’ve seen from the I Get Wet album… I’m not that same person. I don’t just mean that in a philosophical or conceptual way. It’s not the same person at all.”
You might wonder at a committee which would have created such a two dimensional and annoying character, and it's hard to see that it makes much of a difference to people who liked the result. It does remind us of the question of what the hell the NME got so bloody excited over him for in the first place, though.
