my old bass player from my high school band had something to do with Weezer. He wasn't the original bass player, but I think he might have played with them later or maybe he produced them. I dunno.. I do know that he was in a band called "Letters to Cleo" which enjoyed a little success in the early 90's.
His name is Scott Riebling, and he's making a name for himself as a producer in Boston these days (I think he went to Berklee). He was a great player even in high school. His older brother Eric plays, too.
