Several episodes have different music used in different scenes, either a pop song by Tahiti or standard series music. These episodes sometimes appear on home video or different TV airings. For example, in the episode "Knock, Knock", when the Ghostbusters are on the train, sometimes you'll "The Bogeyman" by Tahiti, and sometimes you'll hear a remix of the theme song. The long-running Ghostbusters' website Spook Central (SpookCentral.tk) has a detailed list of these Alternate Episodes.
