Movie: Airheads (1994)

Tagline: The music. The legend. The hostage situation.
Trivia: The Lone Rangers' hit single "Degenerated" is actually a song by 1980s punk-turned-metal group Reagan Youth.
Goofs: Revealing mistakes: In the last scene when the band is trashing the stage and instruments, Chaz pretends to smash a PRS guitar, actually just slowing his swing to not hit the full stack guitar amp, only pretending to smash it.
"Chazz, Rex, and Pip are a band known as The Lone Rangers, and all they're looking for is some attention. But when they take over a radio station with fake guns in order to get their song played over the airwaves, they get a little more than they bargained for.
