Tommy famously uses drum kit stunts during the band's shows. On Mötley Crüe's 2011 tour, Tommy played a drum solo, turning upside down in his 360 drum roller coaster, sometimes even inviting a fan to ride along.

But engineer Scott King has sent a legal letter to the band's attorneys, alleging he pitched a similar plan to Tommy Lee in 1991 but the idea was dismissed.

But the attorneys have fired a letter in response, insisting that Tommy never received a pitch and even if he did, Scott's rollercoaster model is totally different from the stationary "drum ring" used by Tommy.

So far, no lawsuit has been filed.

It's not the first time that Tommy Lee's played a drum solo upside down. Watch this video footage from 1987:

Jack Valentine, drummer in WhiteHorse (the first incarnation of Mötley Crüe) and The Flying Circus, plus Mick Mars (Mötley Crüe guitarist) built an upside down drum riser in 1974, possibly the world's first. Here's footage from 1975:
