Do any of the Disc-o-tech records that Motown released between '75 and '76 feature exclusive mixes of certain tracks? I know that from my Dancing Machine/Moving Violation Jackson CD, that 'Forever Came Today' on the MV album is a different mix from the Disc-o-tech #3 record (included as a bonus cut on the CD) as it is mostly instrumental in the second half of the track, unlike the original LP mix.

Any other unique mixes?
