It seems strange to me that Bohannon was connected with Motown acts from around 1964 & after moving to Detroit led the Motown Revue tour band BUT never seemed to cut any tracks for Motown.
The earlier Motown touring bands; Popcorn & the Mohawks, EVD & the Funk Brothers and the Choker Campbell Band were all allowed to record in their own right.
Did Bohannon ever play on tracks as a member of the Hitsville studio band ?
I guess it's just pure coincidence that Hamilton was at Motown not long after George Bohannon and that they weren't actually related in any way.
