Here is the short Main Title Theme Horner wrote for this 1985 TV-Movie Starring Molly Ringwald, Zach Galligan and River Phoenix, about teenage suicide.
Yes, very COCOON like, especially in that 2nd cue I posted. The film is on youtube in it's entirety. I just skipped around to find the score. Not much score. Some short tinkling, quiet piano cues. Main and End Titles and that Sad Cue I posted. Possibly 7 - 15 minutes of score.
