Count me among the few who saw INCHON in the theaters. One of my Catholic grade school buddies and I saw it at the three screen West Plaza Cinemas in Aurora, IL.
I too remember loving the music (having gotten hooked on film scores very young when my older brothers and sisters went through a few copies of the JAWS & STAR WARS LPs).
Interesting release of THE IDOLMAKER LP from Varese. It was originally on A&M Records. I saw the film a few years ago, and the songs, while not all precisely in the period of the 1950s (some late 1970s disco beats sneak in there), are engaging enough to want to hear outside of the film.
