Over The Wall - An MTV documentary.  (Broadcast on May 15, 1988)
This is a favorite for "clip" tapes.  Luckily, I was able to tape
it from MTV, so I've got an incredible copy.  Wish they'd play it
again so I could tape it in stereo, though...

Videos: Brain Damage/Eclipse, Welcome To The Machine, Another
Brick In The Wall Part 2, Signs Of Life (partial), Learning To
Fly, Dogs Of War, On The Turning Away.

Total Length - 45 min

  Another Brick is straight from the movie The Wall.  Dogs Of War
and On The Turning Away are both from Delicate Sound Of Thunder. 
But, the others are all cool conceptual videos that were used as
backdrop footage during the concerts.

  The rest of the documentary is a mixture of interviews and
brief clips of other videos.  For instance, there are short
pieces from the Point Me At The Sky video, the Pigs On The Wing
video, and a weird film of Syd running on a beach.  This is an
extraordinary documentary.  Seek it out.
