#Pyromania40 Facts for 40 Years! | What was special about the LA Forum Pyromania Tour stop? The show at the LA Forum was a hot ticket. Rock royalty like Heart's Nancy Wilson and Van Halen's David Lee Roth and Alex Van Halen were in attendance. Queen's Brian May even joined the band onstage for a song. The most special guests of all were the Def Leppard parents who flew in for support and some California sightseeing. "I remember it with such fondness, because it was nice for them, you know? It wasn't just about seeing their sons. It was the camaraderie within the group." - Rick Savage
