22. "Singin' in the Rain" dance style: TAP. What a production number! I found this tidbit: "The title number, filmed on a street set two blocks long on the MGM backlot, took seven days to film, with six hours of fake rain each day. The water was mixed with milk to make it show better on camera, but the mixture made Kelly’s wool suit shrink. The perpetually drenched Kelly had a bad cold and fever the whole time. Dancers Gwen Verdon, Jeanne Coyne, and Carol Haney dubbed Kelly’s tap sounds and splashing noises in post-production." >Huffington Post<
