 The end credit music is different on all video and the recent DVD release  when compared to the theatrical and the HBO/Cinemax airing in the 80s. The  theatrical and HBO had on the end credits the suspense music from the film,  which then changes to a Glenn Miller jazz score, while the suspense music is  heard in the background, creeping up faintly, until when the cast names start  rolling, then the suspense music takes over, ending exactly when the credit  ends. However, all video release of this, as well as the DVD, the end credit  music is now the rehash of the beginning credit sequence music, you can tell  its tacked in, for they fade the music early when the credit ends.
