And in ESB after Yoda's Line "Du wirst Angst haben" came a little piece of music (as the Star Destroyer is shooting asteroids, also gone since 1997), which sounds like a fade out of another piece. Does anyone know what piece that was?
That's another part that have always been without music, IIRC another bold statement of the Imperial March was written for that scene and it can be heard on the soundtrack CD.
