Ashba and Sixx AM bandmate James Michael share their most embarrassing spinal Tap moments in an interview with Ultimate Classic Rock. Ashba says: "I have tons, but the one that stands out is when I caught on fire by pyro. I was out there playing, and I just remember thinking, 'Wow, it's getting really hot up here.'

"It looked like Richard had seen a ghost - he just stopped playing. Evidently, I had a flame going all the way up my back, like way above my head. He's like putting me out and I'm trying to play.

"It burned a hole in the ass of my jeans and one of the techs thought it was a great idea to put duct tape over it to get me through the show. Which was clever until I had to rip it off, and it literally took all the skin off with it."
