There is a song at the beginning of one of the episodes that I was wondering about. It's at the beginning of the episode where Jack's grandfather comes to visit him and thinks Jack is a doctor. Cindy brings over some albums and Janet starts dancing and Cindy makes fun of her out of date dance moves. Does anyone know if this song was a real one (not just made up for the episode) and if it's real what the name and artist are? Thanks!
