Hi, Tom. Congratulations to you and your continued studies. I regret I missed your birthday, revealed by our fellow friend Sansradio. I hope things in the UK are improving, pandemic-wise. I wish I could provide verifiable info to assist you, but I am only in possession of scurrilous rumor which I will not pass on. It will be interesting to see what you find [[speaking as the 3rd gayest man on earth ...) but I fear that The Closet Door was shut so firmly during Motown's glory years that info may not be forthcoming. There have been a scholarly tome or two about the subject and I shall try to get the ISBN info to you - Best always!
