Close inspection of the tracks reveals they were taken from 1940's Freddie Mitchell masters from the Derby label and given new titles.
The album jacket, with a photo of cruising white teenagers, describes this band but, there was never any Hen Gates and never any Gators.
The Masterseal LP's have been re-released on CD with the original album photo, but now the text has the words "with Freddie Mitchell" on the cover.
Mitchell's name does not appear on the original 1957 vinyl issue.
There actually was a jazz pianist nicknamed Hen Gates who was a bebop musician of the early to mid-40's, but there is no relation to this artist.
