Steve Perry ruined Journey? What? He is only on the most incredible voices EVER in rock, and I dare anyone who heard them/him live to argue. In form, his voice was spectacularly good.

"More Than A Feeling" by Boston.
Break out the Pepto Bismol

Anything with Getty Lee or Axl Rose singing. The horror, the horror...

"Horse w no name" by America. It gives me hives!

The way Steve Perry sings "in the cit-ty" (I don't know the name of the song, but it's one of Journey's big hits) makes me want to punch him in the face. But agreed, Getty Lee, Axle Rose, and Rod Stewart are right up there.

I saw The Jeff Beck Group on the first U.S. tour, and during one of Jeff's extended solos, Rod, apparently not knowing what to do with himself, ambled back to the guitar rack and strapped on one of them. He then began strumming chords as he made his way back to the front of the stage, at which point Jeff noticed. Jeff stopped playing, just standing there staring at Rod, until he finally went up to the mic and, with his voice just dripping with contempt, said "It's not even plugged in. Bloody wanker".
