He lost his voice due to alcoholism, drug use (cocaine), steroids injected into his vocal cords (to help him get through tours), and over use during Journey's peak years.
Check out the Bill Graham memorial tribute concert that Perry, Schon, and Cain performed at. They had to tune down at least a whole step (it may have been more) so that Perry could try to sing in key. He was absolutely horrible.
When Perry rejoined Journey prior to recording "Trial By Fire" they jammed on some of the old songs. Keys had to be lowered on all of the songs.
There was no "Trial By Fire" tour due to Perry knowing that he could no longer sing the Journey catalog in the original keys and that he wouldn't be able to get through a tour.
Herbie Herbert, Schon, and Cain know for sure. Perry knows, but dodges the questions. He's "been thinking about recording and touring" since he was fired from Journey after refusing to tour in support of "Trial By Fire".
I'm aware of the keys being lowered at the Graham performance and the shape of his voice for TBF (obviously he'd lost some of range by that point, but who wouldn't at that age?), but regarding Steve losing his voice due to alcohol/drugs and/or steroids. I don't know that I've heard about that. Can anyone shed some light? Is this BS?
(Not looking to start any trouble -- the guy who posted this is a major downer on all subjects. I figured if any board would be the place to get some info on this, it'd be here...)
