KISS has been eligible for induction into the Rock and Roll Hall of Fame since 1999, but they were never "darlings" of the critics.

It was the pressure of their fans, the KISS Army, that will get them inducted Thursday night into the Rock and Roll Hall of Fame.

40 years together, millions of albums sold, marketing mavens, in-fighting, numerous members, pyrotechnics, spitting blood, fire (and more), but sadly it's the group's decision not to perform at the Rock and Roll Hall of Fame Induction Ceremony that has everyone talking.

Paul Stanley continues to speak out against the Hall who decided only the original lineup is being recognized.  He says, "I'm playing the game only because there are still some fans who see it as validation and vindication.  These people have fought for decades...I'm celebrating 40 years..."

Accepting the honor at the ceremony will be Gene Simmons, Ace Frehley, Peter Criss and Paul Stanley, to which Frehley says, "Paul and Gene have me and Peter boxed they're gonna have the first word and the last word...I don't care about that.  I'm just gonna get up there and be funny..."

Ace confirmed he will perform during the all-star jam at the end of the night.  The ceremony is being held at the Barclays Center in Brooklyn, New York and will be televised on HBO on May 31st.
