Uh... 78 sounds a bit early, but may be the release date of the original Media Music release. Do you know where you have these dates from?
Well, I don't really know to be honest… but some of the cover scans I have for these Capitols have handwritten notations on the back that indicate when particular cuts were used, etc. MMSE-1 (Today's Deluxe Sound), for example, has two cuts dated _1979_ (Nov. and Dec.). I have this LP catalogued as _1978_
