Trying to find a Dave Allen sketch.

I'm trying to find a sketch by Dave Allen. As far as I remember it is set in a wild west saloon, and the joke involves two cowboys. One cowboy walks into the bar and proclaims he is the fastest draw in the west. A second cowboy jumps up and shoots the first and says "Well what are you doing out here in the east" I've looked on youtube but can't see it. Does anyone know where else it might be or perhaps can find it on youtube.
