JR.WALKER and THE ALL STARS

Junior Walker and the All Stars — Billy Nyx, drums; Willie Woods, guitar; Vic Thomas, organ — have been a chart-topping combo since “Shotgun” won a Grammy Award as the best rhythm-and-blues recording of 1965. Supposedly written in a Benton Harbor, Michigan hotel room, “Shotgun” was much more than one of the most danceable records of all time.
