Go Green Ranger Go, The Mighty Morphin Power Rangers' Green Ranger theme is the first theme song given to a separate ranger aside from the consistent five Mighty Morphin Power Rangers. Used for the first two seasons of the show and discontinued with the start of the third, a first version plays during Rita's reign in the first season and a second version was used after Lord Zedd becomes the main villain in the second season. Both versions include Goldar as an antagonist in the track. The track was composed by Ron Wasserman (a.k.a. Aaron Waters). The sample of the song first appears at the end of "Return of an Old Friend, Part 1".
