An old friend points me toward this video of one of the greatest blues shouters of all time, Big Joe Turner, singing (ie, lip syncing) Feelin’ Happy. The racial segregation of the era is clear from the clip, but man, what a groove and what a voice. FTR, rock and roll starts here.
If this don’t turn you on, you may not have a switch.
Let the good times roll,
Let the good times fly!
