According to the League of American Orchestras, he was the second most frequently performed American composer by U.S. orchestras in 2008–09 behind Copland, and he was the 16th most frequently performed composer overall by U.S. orchestras. (Some performances were probably due to the 2008 90th anniversary of his birth.) His most popular pieces were the "Overture to Candide", the "Symphonic Dances from West Side Story", the "Serenade after Plato's "Symposium"" and the "Three Dance Episodes from On the Town". His shows "West Side Story", "On the Town", "Wonderful Town" and "Candide" are regularly performed, and his symphonies and concert works are programmed from time to time by orchestras around the world. Since his death many of his works have been commercially recorded by artists other than himself. The "Serenade", which has been recorded more than 10 times, is probably his most recorded work not taken from an actual theatre piece.
