Conductor-composer Leonard Bernstein plays a kazoo

With a cigarette in his hand, conductor-composer Leonard Bernstein still manages to play a kazoo during a rehearsal of his "Mass" at the John F. Kennedy Center for the Performing Arts in Washington on September 2, 1971. A scene from "Mass," which Bernstein wrote and will conduct, contains a segment in which a kazoo is played. (UPI Photo/Files)
