Comment by 55bluesman ●:
According to Brain McFadden's highly recommended book "Budget LP's That Saved The Roots Of Rock And Roll" (
see here), page 129 this Don & Eddie LP comes first before the Billy Boyd Crown-LP.
Behind all those recordings stands one man: Jerry Cole. The LP's were issued under different synonyms (Billy Boyd, Don & Eddie, Don Dailey....), sometimes the song titles were also changed.
