I Dream of Jeannie - Season 4 - Eps 24: Jeannie-Go-Round
Locking Jeannie in her bottle, her wicked lookalike sister Jeannie II trails Tony to the Cocoa Beach Cabana. In her efforts to win Tony's affections, Jeannie II also replaces the nightclub's regular singer and renders a seductive ballad ("Electric Days, Electric Nights"). Alas, from this point forward everything goes wrong, with Tony being publicly embarrassed and Dr. Bellows virtually being hand-delivered enough evidence to wash Tony out of the space program!

While on a mission, American astronaut Captain Tony Nelson is forced to make an emergency landing that will forever change his life.
