In the topsy-turvy world of heavy rock, there are slobbering dumbshits like Ratt vocalist Stephen Pearcy and there are rock-solid showstealers/-savers like Ratt rhythm guitarist John Corabi (ex-Motley Crue, The Scream). From Blabbermouth:
Ratt was forced to cut short its Friday, June 27 concert in Monterrey, Mexico, after lead singer Stephen Pearcy appeared to be incapacitated and was unable to complete the show. At one point, Pearcy lost his balance and fell into the crowd before being helped back to the stage by the venue's security personnel, only to fall backwards. He then got up and resumed singing as if nothing had happened.After performing for about 50 minutes, the band abruptly left the stage and reappeared a few minutes later, this time without Pearcy. Rhythm guitarist John Corabi, who is best known for having replaced Vince Neil as the frontman for Motley Crue in the early 1990s, apologized to the crowd and blamed the mishap on "jet lag" before taking over on lead vocals for a few tracks, including a couple of solo numbers and the Ratt songs "Body Talk" and "Round and Round".
Boy, it's sad that Ratt guitarist Warren DeMartini's livelihood is tied to batshit insane Pearcy. The universally-loved Corabi, on the other hand, is especially cool halfway through this clip when he gently reminds the Monterrey crowd of rock concert etiquette guidelines: 'Drinking? Ok. Fucking? Ok. Fighting? No fighting!'
