I am not sure if this has been asked on past threads [[I am new to the site) but were the various volumes of the Motown "A COLLECTION OF 16 BIG HITS" series [[including the first volume known as "A PACKAGE OF....") from the 1960s [[primarily) ever issued on CD? It would be nice to have a box set of these with the mono/stereo versions of the earlier volumes. I think some volumes have different takes of the same song on mono vs. stereo.
