Yes Jo, you're kinda 'spot on'...they started their story-telling around 1979/80 with that book "Elvis - We Love You Tender" which is a contradiction in terms where the title is concerned.
The book, as told to Martin Torgoff (possibly another Steve Dunleavy?), appeared to be written to put the Stanley Brother's 'nutcase' Mother, Dee on the 'Presley Map'. Some of the stuff I've read and heard about her, well...what can we say? I think she would have done a better job than Glenn Close in that 'Dalmations' movie.
And then of course there is the 'runt' of the litter - 'Diddy David' or as he is now known - "The Headhunter"...Jeez, that guy talks a good case - almost hypnotizes you...as Preachers do. The guy is very much a business man but I'm convinced he can't really remember very much about the years between 1972 and 1977, so he just makes it up.
I think oldest brother, Billy has turned out to be the best of the bunch - but please correct me if I'm wrong.
They're a strange 'quartet' are the Stanleys...put them in the same league as the Pritchett Sisters - Donna & Susie (Nash & Earl's Daughters).
