FWIW, He had legally changed his name to Michael a while back.
It was done in 1984 before his massive fame hit.
I had to look it up because I knew Marvin was a
his birth name but I didn’t know when it occurred that he switched.
Oddly my ex lived in the same area in CT while she raised her daughter who went to school with Pearl, his daughter. He was quite the
character, she reported to me. She attended a party or two at his home. I think she said she met Alice Cooper, etc. Diana Ross and her daughter also lived there and may have attended such get-togethers. Circa 1987, I think.
