"Gospel Stars" is the only one I own and was aware of before your post, which I'm glad you did as now I have yet another record to search for! I was totally unaware of the Motortown Revue Vol 2 audition copy.

I totally get what you're saying though about so many sellers erroneously listing all the early white label Tamla LP releases as promos. It drives me up the wall but by the same token there are some early logo Tamla 45's that were pressed with white labels that do not mention DJ, promotional or audition copy, but I've always assumed they are/were promos. Ah the joys of collecting all the variations you can find!
