the series finale. That episode did not air until the show entered syndication. Theme music For the first season, the song "Best of Friends", composed by Linda Creed and Barry De Vorzon and performed by the Thrasher Brothers, served as the series' theme song. More specifically, the instrumental version of "Best of Friends" appeared at the beginning of each episode (and short clips of the instrumental version occasionally appeared within episodes, even after the first season), while the lyrical version appeared at the conclusion of each episode. At the beginning of the second season, the second and more recognizable instrumental theme song, composed by Barry De Vorzon (who had previously composed the theme to the 1970s police drama, S.W.A.T.) and Michael Towers, was introduced. The theme consists primarily of an electric bottle-slide guitar lead with a saxophone interlude and remained until the last episode of the final season. Both theme songs had extended versions released; the Thrasher Brothers in 1982, and De Vorzon/Towers's version in 1984. Crossover with Magnum, P.I. The episode "Emeralds Are Not a Girl's Best Friend" concludes a crossover that begins on the Magnum, P.I. episode "Ki'is Don't Lie", wherein Higgins helps the Simons track the woman with stolen Hawaiian artifacts to Latin America. For repeat and syndication purposes, a second conclusion was also shot, wherein the fleeing villain is caught, allowing the Magnum episode to be wrapped up and the episode to be rerun as a "stand alone" episode. Consequently, the Simon & Simon concluding hour, "Emeralds Are Not a Girl's Best Friend", did not appear in reruns for many years, nor did the original broadcast version of "Ki'Is Don't Lie". Both original versions have since been released on DVD. Additionally, A.J. Simon appeared on the Whiz Kids episode "Deadly Access". In return, the Whiz Kids characters Richie Adler, Hamilton Parker, Jeremy Saldino, Alice Parker, and Irene Adler appeared on the Simon & Simon episode "Fly the Alibi Skies" the following night. Home media On October 10, 2006, Universal Pictures Home Entertainment released the first season of Simon & Simon on DVD in Region 1. Due to poor sales, no subsequent seasons were immediately released, because of the synthesized background music scores, where it had entirely replaced the original music scores, due to music licensing issues. In Fall 2008, Shout! Factory announced that they had acquired the distribution rights through an agreement with Universal Pictures Home
