Los Angeles glam metal jokesters STEEL PANTHER have revealed that they will perform at the wedding of NICKELBACK frontman Chad Kroeger and singer-songwriter Avril Lavigne.A video message from STEEL PANTHER guitarist Satchel and bassist Lexxi Foxx in which share their excitement about taking part in such an event can be seen below. Kroeger contributed guest vocals to and collaborated on the song "It Won't Suck Itself" from STEEL PANTHER's 2011 album, "Balls Out". "We play a lot of shows, and we have weekly residencies in L.A. and Hollywood," STEEL PANTHER drummer Stix Zadinia told Audio Ink Radio. "Chad was in L.A. for a while, and he would come to our shows and get up onstage and jam. We got to know him, and at one of the shows, we were like, 'Dude, we should write together!'" Kroeger did the classic, "Yeah, bro!" But for a while, nothing came of the friendly exchange. "We kept saying it enough times that finally, we were like, 'Let's do it.'" When STEEL PANTHER was in Vancouver, they called Kroeger. "We started writing the song together from scratch, and it's a true collaboration," Zadinia said. "It wasn't a riff lying around that hadn't been used yet or something that was recycled. We walked out of there with the core of what is that song."
