Rocker David Crosby is hoping for one more Crosby, Stills, Nash & Young tour before diabetes and hepatitis C get the better of him.

The four-piece parted ways in 1976, but Crosby, Stephen Stills and Graham Nash have often regrouped without Neil Young, and in recent years there have been various reports suggesting the quartet was planning a get together.

And now Crosby, 71, tells Rolling Stone he's one of the people hoping for full Csny reunion tour.

He says, "Look, I have maybe 10 more years, if I'm lucky. I have hepatitis C, diabetes and heart disease. I'm managing them. I'm going to the gym three days a week, I'm feeling strong and I can still make audiences feel great.

"My dream? One more tour with Crosby, Stills and Nash and my friend Neil. From there, I'd be fine. I'd be able to sail. I'd live. And I'd be happy."

Ironically, a live album commemorating Csny's last tour will be released later this year (13).
