Billy Hutch Harmonica and Orchestra

"Eefin" was a 19th-century hillbilly musical style that enabled non-musicians to participate in hoedowns. It manifested itself as hand-slaps across the thigh, and vocal effects such as grunts, animal sounds, Bronx cheers, and, most identifiably, a wheezy in-and-out noise something like "eef - ahhh - eef - ahhh." Modern America was exposed to this forgotten art form in the 1970s courtesy of Hee Haw, one of TV's most inexplicable successes. Jimmy Riddle
