Grand Slam Opera is a 1936 American short comedy film starring Buster Keaton and produced by Educational Pictures.
Elmer dashes back to the studio (via train, car, and on foot) and his new prosperity and popularity convince the girl to finally go on a date with him.
Grand Slam Opera is a satire of the Major Bowes amateur hour, heard weekly on network radio.
[1] "Colonel Crow" parodies "Major Bowes," and the "dancing directly over the downstairs neighbor's room" satirizes the same episode in the Fred Astaire-Ginger Rogers musical Top Hat.
The "Anvil Chorus" scene harks back to an old vaudeville routine, in which Keaton and his father exchanged slapstick blows in time to the music.
