Because of the talk of alternate music for ROTJ’s ending, I went for a look for some lesser-known Williams music to put to this scene. Here’s a fun combo:

Start this track at 1:38

and play it concurrently with this from 0:55

In all seriousness, I think what’s missing from the Yub Nub ending is a bit more of the underlying instrumentality that appears near the end of the scene. If someone recorded and overlaid an orchestra section which gradually faded in throughout the scene, it would have been perfect. It doesn’t even need to be complicated, a simple melody in strings and brass that follows the vocalists would suffice. As it stands, the ghosts just appear to the sound of tribal drums without any fanfare, and what little there is comes in too late.
