The Columbia Gilbert and Sullivan Society will present An Evening of Gilbert and Sullivan Saturday at Agassiz Theatre. Excerpts from Pirates of Penzance, Ruddigore, Patience, and Yeomen of the Guard will be featured.

Originally, the group was scheduled to perform Ruddigore in exchange for the New York visit of Harvard Gilbert and Sullivan Player's Yeomen of the Guard.

Princess Ida will be the spring production of the Gilbert and Sullivan Players, Joseph H. Gardner '60, president, announced last night.
