Chubby Checker wasn't alone in the "Dance" songs catagory. His Label, Cameo-Parkway, had HUGE success with the genre, fueled by appearances with easy access to a national audience on Dick Clark's American Bandstand, televised from Philly. Others include Candy and the Kisses "The 81", Billy Abbot "Come on and Dance With Me", Checker/Dee Dee Sharp "Slow Twistin'", Don Covay's "Popeye Waddle", Dovells' "Bristol Stomp" / "Cant' Sit Down", Bobby Rydell "Cha-Cha-Cha", The Marlins "Everybody Do The Swim", Dee Dee Sharp "Mashed Potato Time"...you get the idea.
But my favorite on the label were The Tymes(pre-RCA), sweet harmonies, silky lead, basic, non Phil Spector type arrangements.
