Fozzy frontman Chris Jericho has defended Paul Stanley's vocal performance on Kiss' current "End Of The Road" tour, explaining that the veteran rock singer "has nothing to prove to anybody."

Ever since Kiss launched its farewell trek in late January, there have been persistent online rumors about Stanley allegedly lip-syncing to pre-recorded vocals. The speculation stemmed from the fact that Stanley had been struggling to hit the high notes in many of the band's classic songs for a number of years.

Appearing on the latest episode of the "Three Sides Of The Coin" podcast, Jericho said flatly that Stanley is "singing his ass off as much as he possibly can." He added, "Paul Stanley has nothing to prove to anybody. He's one of the greatest rock and roll singers of all time. I think that's something that anybody would say. I would much rather have him use the technology that's available to not sound like he's hurting himself, which then makes me not enjoy the show as much."

Jericho acknowledged that Kiss is most likely doing what many other artists have done, which is incorporate backing tracks and click tracks to their performances. He explained, "Paul is singing -- he's singing his ass off as much as he possibly can. But if it's a rough time, they're just sweetening it a bit . . . I'm not saying that's what they're doing, 'cause I'm not the sound mixer, but that's my guess as to what's happening."

Fozzy has been touring in support of its seventh studio album, Judas, which has yielded a Top Five rock radio hit in the title track.
