SAN RAFAEL, Calif. (AP) — The bass player for the Grateful Dead has bladder cancer. Phil Lesh announced his condition on the Facebook page of his California restaurant and concert hall. Lesh says he was diagnosed earlier this month — and says he has been undergoing test at the Mayo Clinic in Arizona. He says he will have the tumors removed — but feels “very fortunate” that that doctors feel the tumors aren’t aggressive and that there’s no sign they have spread.
