Back Alley Oproar is a Warner Bros. Merrie Melodies animated short directed by Friz Freleng. The short was released on March 27, 1948, and features Sylvester and Elmer Fudd. The title is a play on "uproar" and "opera". This is a rare exception for Sylvester as he wins in this cartoon. It is a remake of Freleng's Notes to You (1941).
