A concert commemorating the 40th anniversary of the recording of Johnny Cash at Folsom Prison has been canceled. The tribute concert, which was to feature Cash's drummer, W.S. "Fluke" Holland, was to have taken place Sunday (Jan. 13) at Folsom State Prison in Folsom, Calif., at the same cafeteria where Cash performed on Jan. 13, 1968. The event was canceled following security concerns and disagreements between event organizers and prison officials. The show was being promoted by Jonathan Holiff, the son of one of Cash's former managers, Saul Holiff.
