Guitarist Ace Frehley is confident Thursday’s KISS reunion at the Rock & Roll Hall of Fame Induction Ceremony will be a harmonious affair, despite the bandmates’ public attacks of each other.

He’ll join founding members Paul Stanley and Gene Simmons and bandmate Peter Criss, alongside the group’s current drummer and guitarist and another ex-member, Bruce Kulick, for the honor in New York – and he insists the group’s big night won’t become a big drama, no matter what they’ve said about each other in memoirs and interviews.

He tells VH1, “We say good things about each other and we say bad things about each other… but it is what it is. It’s rock and roll. I mean, if all we did was pat each other on the back for every book, people would say, ‘That’s a boring book.’

“They want to hear the dirt. I’ve got plenty of dirt.

“(But) believe it or not, every time the four of us (Stanley, Frehley, Simmons and Criss) get together, even though it’s been a long span of time, we’re still brothers in rock and roll. At least that’s the way I feel. If it’s not going to be that way, I’d be surprised.”

Stanley and Simmons have refused to perform at the gala following the band’s Hall of Fame induction – because current bandmates Tommy Thayer and Eric Singer won’t be inducted alongside them.

Hall of Fame officials insisted only the original line-up should be honored.
