Illness forces Crosby, Nash to cancel tour

PASADENA, Calif., Feb. 19 (UPI) -- Veteran rockers David Crosby and Graham Nash, half of Crosby, Stills, Nash and Young, canceled their U.S. tour because of Crosby's medical problems.

"Medical issues that have arisen for member David Crosby," the Web site Crosbynash.com said.

The tour was scheduled to kick off next month in Shawnee, Okla., and end in April in Niagara Falls, N.Y.

"We deeply regret that the band will not be able to embark on this tour as scheduled," the duo's manager Donald Miller said on the site. "At this time, we thank you for your understanding and the band looks forward to seeing you this fall."

Crosby has had a history of medical issues, including hepatitis C and a liver transplant in 1995.
