BULLETBOYS frontman Marq Torien hopped onstage with glam-metal jokers STEEL PANTHER on Sunday night (April 24) during the the Rainbow Bar & Grill 50th-anniversary bash in West Hollywood, California to perform the BULLETBOYS song “Smooth Up In Ya”.

A documentary about the Rainbow Bar & Grill was released in 2019 called “The Rainbow”, which featured Lemmy Killmister, Ozzy Osbourne, Slash, Gene Simmons and countless others.
Both legendary venues, being the Whisky A-Go-Go and The Rainbow, were founded by Mario Maglieri.
