the thing about the Motown labels was everything after the four majors

were specialty labels like the Jazz Workshop was obviously Jazz.........the others were more re-issue labels.....except in the case or Rare Earth, which was for their white artists...what irony that the biggest Black owned label had a label for white artists, much like the main stream labels that had susids for black groups. The Irony here is huge.
Example: Columbia maybe the biggest Label of It's day had Mitch Miller as head of A&R in the 50's...he fought against signing Rock N' Roll Acts, much less...Black artists...so Columbia used its sudsid OKEH records which was puchsed specifically for "Race Records", or "R&B" or "Blues Shouters" as they were referred to in those days. Okeh was puchased form Otto Hienemann in 1920,and scored with Black Jazz Artist Mamie Smith, at that time it was part of the Odeon (still in existence today, primarily as a re-issue label, for Polygram) Empire back then. Eventually all the Majors had susids for their black rosters...and then the Indys started popping up Liberty, Specialty, Imperial, Modern.....all Los Angeles Labels and they were signing black and white artists, and that turned out to be the end of sudsids by the big labels(Capitol, Decca, Columbia, RCA, etc) as they had to follow trend.
yes the Four Seasons started on VJ and early Four Season Lps which featured cross promotion with the Beatles, are today, among the most sought after as Beatles Collectibles. There is an EP I believe called Four By Four 4 cuts by the Beatles and 4 cuts Four Seasons that is Huge in the Collectors world. The LP "Intoroducing The Beatles" that was issued with 3-4 variances of the Back cover is the second most sought after Beatles Lp second only to the "Butcher Cover" LP, is due in part to the Four Seasons LPs featured on of one the variance issues. "Introducing The Beatles" on VJ is also the most couterfeited LP In history, so you have to be careful when you are buying one. The Four Seasons eventually went to Phillips , which If I am not mistaken was a sudsid of Mercury Records, actually it was the other was around Phillips bought Mercury records.
