The band axed a European tour last year (13) due to the veteran rocker's health scare, and he subsequently underwent heart surgery. Lemmy was left out of action for months as he recovered, and a planned comeback at the beginning of the year stalled when he fell ill again.
The veteran rocker is now bouncing back with a number of summer gigs with Motorhead, and he has credited former Guns N' Roses star Slash with helping him through the difficult times.
He tells Rolling Stone magazine, "He was at my house more than he's ever been before, encouraging me. He's a really f**king good guy."
Lemmy goes on to insist he is prepared to give up his music career if he finds himself unable to perform properly, adding, "You should deliver. But if I can't deliver, I'm never going to be a figurehead up there and just play for money. I could never do that. I've seen people do it, and it's just frightful. I'm old, you know. In two years I'm 70, which is ridiculous. How did that happen to me?"
