 He featured lots of Gershwin tunes on his show. He also featured Irving Berlin, Aaron Copeland, Rodgers and Hammerstein, Jerome Kern, Lorenz Hart and Yip Harburg (who wrote "Over the Rainbow"), and others.

He occasionally would have his Irish tenor, Joe Feeny, sing a jewish medley from the high holidays or have his cast do a Chanuka skit. Selections from Fiddler on the Roof were always popular with his audiences.
