During the kickoff date of Mötley Crüe’s stadium tour with Def Leppard, Poison, and Joan Jett at Suntrust Park in Atlanta, GA, the band were joined onstage by Machine Gun Kelly for a performance of their collaborative track “The Dirt (Est. 1981).” That song was written for the band’s biopic “The Dirt,” which finds Machine Gun Kelly playing drummer Tommy Lee. Notably, Lee didn’t take part in the “The Dirt (Est. 1981)” performance due to broken ribs that caused him to leave the stage after five songs.
