Megadeth
After the band played at Monsters of Rock, Mustaine fired Behler and Young. He also canceled the band's Australian tour. Mustaine later said he did it because he thought "a lot of us were inconsistent because of [drugs]". During Monsters of Rock, Mustaine saw Behler using drugs. He had drummer Nick Menza help Behler as a roadie (someone who helps a band with technical work). Menza replaced Behler in 1989. Young was fired because Mustaine thought he was having an affair with his girlfriend. Young said this was not true.
