Steve Martin on Banjo. Yes, that Steve Martin. One of Hollywood’s legendary funny men, Steve Martin, makes his musical debut at RMA on May 27 playing 5-string banjo with the Steep Canyon Rangers. Two encore performances will follow on May 28. These concerts sold out quickly but a limited number of house seats have been reserved for sale to members at the Chairman’s Circle level or higher, and tickets are still on sale for Rosanne Cash’s ninth concert at RMA. Cash will perform on May 29 with singer/songwriter Marc Cohn.
