According to TMZ.com, MÖTLEY CRÜE drummer Tommy Lee has been threatened with legal action by a Los Angeles engineer who claims that Lee stole his idea for a drum kit roller coaster.

Scott King sent a letter to CRÜE's lawyers claiming that he approached the drummer in 1991 to pitch him the idea for roller coaster setup that Lee has been using during the band's shows.

CRÜE's attorneys have since responded to King, insisting that Lee never received a pitch and that the two ideas in question were completely different.

Regarding how the idea of the 360-degree drum roller coaster came about, Tommy stated last year, "[It] came about from when I was a kid going to concerts. Whenever the drummer started his drum solo, I wondered why people would leave to go get a beer, buy a t-shirt, restroom, whatever!! I wanted to show people what happens behind the drum set, so I decided to expose it all by flipping the drums vertical, upside-down making them disappear and fly over the audience's heads! MÖTLEY CRÜE brings you on a thrill ride, jump on the 360! Let's do this! By the way, it's really fucking difficult playing while on this ride!"
