These would comprise nearly every currently available stereo Floyd track Syd is either on or ever been rumored to be on. Alternate mixes were left off for reasons of space (and if the alternate didn't produce an interesting OOPS mix). "See Saw" and "Jugband Blues" were also left off, because in OOPS much of the track is very quite, with occasional jumps in volume. It all has to do with where things were panned originally, and that can't be changed.
In the left channel of each track is an OOPS mix produced by inverting the left channel of the original, and the right channel contains a right channel OOPS inversion. As it turns out, these produce the same mix, and one channel is a mirror image of the other. (Identical, but with the polarity reversed.)
