Lots of great info on this thread about many folk involved with GW.
One of those being Sonny Sanders. Sonny must have been quite switched on (business wise) as he was already getting into running labels as early as 1962 (when he was only 23 years old). Along with Robert Bateman, he had formed the Satintones in Detroit in 1957 (when 18 years old) and they were signed to Motown. But he soon moved on from Motown & with Bateman started SonBert Records (part of Correc-Tone) in 62. He was also working with the likes of Wilson Pickett, James Velvet, Gino Washington (all for Correc-Tone) and Bobby Lee Watson (Maureen). From there, he was onto working at GW and then off to Chicago.
Not a bad start to a long & successful music career.
