Sondheim Tribute: Liza Minnelli heads nearly 40 performers set to pay tribute to Stephen Sondheim on Wednesday in “Sondheim: A Celebration at Carnegie Hall,” a sold-out gala focusing on the composer’s diverse compositions in Broadway musicals, jazz, pop, opera and cabaret. Other performers include the American Theater Orchestra, Boys Choir of Harlem, Glenn Close, Robert LaFosse, Beverly Lambert and Patti LuPone. The tribute will air on PBS’ “Great Performances” in March.
