Trival pursuit (quest for useless info!)

Since I have this uncanny need for useless knowledge, I'm searching for the answer to this question.
"Why is it that at a concert the bass player is always stage right, and lead guitar stage left?"
There must be a reason because out of the 100's of concerts and bands I have seen this is always the case.
I know dumb question but a explaination would help me sleep!! (also proves I apparently have too much time on my hands
