I played behind Martha many times as part of a regular 'Motown & 1960's Review'
in the 90's
All the other acts were great people; Drifters, Platters, Brooklyn Bridge, etc. etc.
I was the leader but she would tell to turn down, turn down, until I couldn't hear myself (it wasn't MY playing) her musical director always said the NO bass player after JJ could make her happy - IOW don't take it personally.
Only her & Little Anthony (he never goes without shades - never saw his eyes) had attitudes. I think they got soooo ripped off with little to no royalties that they were bitter.
She was wearin' them moldy wigs way back then? - just sayin'
