Motown's West Coast Office

[jsmith]

Brenda Holloway was mentioned in the Isley Bros thread; her still being pushed in the Motown artists ad at the beginning of 68.
BUT it seems Motown's west coast office never really recovered from Mat Gordon's resignation in late 65.
Who took over there after Matt quit, was it Frank Wilson ? as his is the name that pops up the most on Motown west coast tracks from 66 onwards.
Was the west coast office shut down again before BG relocated the company to LA or did it dump along till then ?
