Do you know The Treniers
? Back in the 40s and 50s, they straddled the lines between jump blues, swing, early rock'n'roll, jazz dance, hep jive and comedy. They were a whole hella fun
, and they happened to be the backing band for what must be the best dance performance Jerry Lewis
ever gave the world. That particular clip, BTW, from a Dean Martin/Jerry Lewis "Colgate Comedy Hour" in 1954, is purported to be the first rock'n'roll performance on national television, and it may well have been.
