Ex-Warrant vocalist Jani Lane has hit the road with Great White, filling in for Jack Russell while he recovers from surgery.

Russell is taking it easy ahead of another operation, after suffering a perforated bowel recently. According to Blabbermouth.com, Russell said, “I’ve felt better, but I’ve felt a hell of a lot worse. Nothing is going to keep me down. This whole thing definitely makes me appreciate life more than I ever have.”

Lane’s former Warrant bandmates are touring with singer Robert Mason (Lynch Mob).
