the song was recorded specifically for the John Hughes film Pretty in Pink,
The single was released as a 7-inch single, a 12-inch single and a shaped picture disc. On the 7-inch single and the picture disc the title track is three minutes and 59 seconds long and the b-side is "Over Your Shoulder". The title track was extended by one minute and 38 seconds for the 12-inch single, to five minutes and 37 seconds, and an extra track, "Bedbugs and Ballyhoo", was added to the b-side.
So I guess it being released as a single with a Grey album B-side and Grey album track led me to believe that it was itself a b-side. But I guess it aint.
