The "genuine blues" as they were meant yo be played. And note it was CBC/Canadian Broadcasting System production. This was during the time when most Black musicians were barred from appearing on national TV in the USA save for Louis Armstrong, Basie, The Duke and a few others. Even Nat Coles weekly US TV show was cancelled. During that time CBC produced a weekly show featuring Sammy Davis Jr. and it was top drawer. just sayin !
