This is kinda old so it may have been discussed before but I recently stumbled across Jack Bruce's (the guy from Cream) thoughts on Led Zeppelin and the O2 reunion recently (I have no idea how or where). He had alot to say about how much he hates Led Zeppelin saying they were "crap." He boasted about how he could sing better than Plant and Clapton could outplay Page and how Cream was 10 times the band that Led Zeppelin was. If anyone has read Eric Clapton's autobiography they'd know that Clapton thought Bruce was an arrogant jerk. He kinda looks like it. In fairness he did say it was blow out of proportion. Anyways, I guess I'm not trying to start a disscussion I just that it was kinda funny how jealous a guy can still get even after he's accomlished as much as Bruce.
