Bruce Springsteen's longtime saxophonist Clarence Clemons has confessed his last tour with the E Street Band was "pure hell" - because he was struggling with knee and hip replacements.
Clemons tells RollingStone.com the constant travelling took its toll on him and by the end of the 2009 trek, he was finding it hard to stand onstage, let alone perform.
He says, "The tour was wonderful musically, but I knew when it was done that I had to have more surgery."
Clemons has since had both his knees replaced again and he underwent spinal fusion surgery.
He adds, "The timing was perfect because it didn't interfere with a lot of stuff that was going on in my life. It made me stronger, and for the past year, I've been in physical therapy a few days a week working my a** off to get back in shape. I'm walking better now, though I still use a cane and crutches. But now I'm having hip problems again. I don't know why."
But the 69 year old insists it will take more than a bit of pain to stop him touring with Springsteen: "As long as my mouth, hands and brain still work I'll be out there doing it. I'm going to keep going 'til I'm not there anymore. This is what's keeping me alive and feeling young and inspired."
And he's also hoping to hit the road with Lady Gaga after collaborating with her on a track for her upcoming album.
Clemons states, "If Bruce and Gaga both needed me around the same time I don't know if you could hold me down to the ground... The thing I'd really love to do is have the chance to go out with both of them."
