Back Alley Oproar

Back Alley Oproar is a Warner Bros. Merrie Melodies Blue Ribbon reissue animated short directed by Friz Freleng and originally released in theaters on March 27, 1948. The short features Sylvester and Elmer Fudd as its main characters, voiced by Mel Blanc and Arthur Q. Bryan respectively. The title is a play on uproar and opera. This is a rare exception for Sylvester as he actually wins in this cartoon.

Elmer eventually dies from explosives from his attempts to get rid of Sylvester. His spirit ends up in Heaven, on a cloud ascending into space. Momentarily he thinks he will finally get some peace and quiet. However, the spirits of Sylvesters nine lives ascend around him, with the male and female cloned ones following them, each with a numeral on its back, singing in a multinonet from Lucia di Lammermoor, with their voices. Just after one of the cat spirits steals his halo, Elmers spirit dives off his cloud and a crash is heard offscreen.The cartoon is a remake of 1941s Notes to You, also directed by Freleng. It has a similar plot, although the ending of the original doesnt have the characters die from an explosion instead, the cat dies from getting shot, and returns as nine singing angels, but the Elmer and Sylvester characters in Notes to You were taken by Porky Pig and an unnamed alley cat the latter bearing a striking resemblance to the cat from Bob Clampetts The Hep Cat. ........
