I never heard of this: Shaun Cassidy sings Illia's theme:
Saw this on Facebook:
Speaking of STAR TREK THE MOTION PICTURE on it's 34th Anniv. This is a demo song by Shawn Cassidy he did on his lunch break whilst filming The Hardy Boys. Another version was done by a female studio singer. Neither was released, composer Jerry Goldsmith was totally opposed, but studios being studios they wanted the back end of Casey Kasem saying "At #12 this week...A Star Beyond Time...from Star Trek The Motion Picture"...and of course money coming from plays of that....
LONG LIVE THE FIGHTERS!
