Jodie Sweetin took dance in real life. The girls that Stephanie is dancing with are Jodie's dance friends. "Mowtown Philly" was choreographed by Jodie Sweetin's real life dance teacher.
The title is a line that starts the song "Broadway Melody Ballet" composed of "The Broadway Melody" from The Broadway Melody (1929) and "Broadway Rhythm" from Broadway Melody of 1936 (1935) (music by Nacio Herb Brown and Lennie Hayton). This combination was used in Singin' in the Rain (1952).
