1) Genesis - Peter Gabriel / Phil Collins
Gabriel - but Phil was ok for a few albums, but then he proceeding to almost single handedly ruin Genesis and the entire music scene in the 80s
2) Van Halen - David Lee Roth / Sammy Hagar
Roth - but I liked the Hagar stuff too
3) Judas Priest - Rob Halford / Tim "Ripper" Owens
umm - is this really up for debate?! Halford
4) Rainbow - Ronnie James Dio / Graham Bonnet / Joe Lynn Turner
Dio but Turner was an upgrade over Bonnet. I saw them with all three singers and the band was always good.
5) AC/DC - Bon Scott / Brian Johnson
Bon Scott - though its probably just my personal preference. I grew up on AC/DC and saw them 5 or 6 times in the late 70s with Bon Scott - Brian Johnson was always the new guy to me and i grew out of them
6) Pink Floyd - Sid Barrett / David Gilmour
7) Black Sabbath - Ozzy Osbourne / Ronnie James Dio / Ian Gillian
Ozzy but I loved the Dio years too. And I'm a huge Deep Purple fan so was not upset with the Gillian era. Saw Sabbath in '78 (ozzy on vocals) with Van Halen opening up and then again on the '80 Heaven and Hell tour with DIo. Both shows were fantastic and i loved both versions of the band.
8) Iron Maiden - Paul Di'Anno / Bruce Dickenson
9) Journey - Greg Rolle / Steve Perry / Steve Augeri / Arnel Pineda
Perry, but I thought the pre-Perry stuff was more interesting.
10) Queen - Freddy Mercury / Paul Rodgers / Adam Lambert
Freddie and this isnt a close call. Paul Rodgers was great in Bad Company but it wasnt really Queen without Freddie
11) Alice in Chains - Layne Staley / William DuVall
12) Fleetwood Mac - Peter Green / Bob Welch / Lindsey Buckingham & Stevie Nicks
