When I first saw UW it was at the Big Day Out in Sydney. I didn't really know much about them (except Lager Lager Lager.. of course). They played a live version which sounds like a combination of both - the pump of Rez with the lyrics of Cowgirl. It was burned in my memory of that night and I knew I had to have it. Unfortunately, neither track from CD quite manages to reproduce the awesomeness of the live combination.
Of course, it helps a little bit to have 5000 people there dancing to it
