Included with the teleplay are two scripted promotional scenes. The first features actor Tom Sullivan sitting in K.I.T.T. telling viewers to catch him "in Knight Rider, Friday! If you can!" before speeding away. The second was to showcase The New Edition who harmonize, while K.I.T.T. provides a drum roll.
The original ending of Knight Song had Michael and K.I.T.T. tuned-in to Charley Conners' live concert while parked outside the theater, after K.I.T.T. insisted they stay to listen.
New Edition members Ralph Tresvant, Ricky Bell, Ronnie Devoe & Michael Bivins guest star in this episode.
The character G. Sanford is named after the third season producer Gerald Sanford.
Michael and K.I.T.T. have a mission waiting in Detroit. They are three days late by the time this case is over.
