In the 1960s, hearthrobs named Bobby were everywhere. Clockwise from top left: Bobby Darin, Bobby Vee, Bobby Rydell, Bobby Goldsboro, Bobby Womack, and Bobby Sherman. And on the soul charts, Bobby Womack (“I’m Lookin’ for a Love”), Bobby Lewis (“Tossin’ and Turnin'”) Bobby Freeman (“Do You Want to Dance”), and Bobby Smith of the Spinners. Country Bobbys included Bobby Goldsboro (“Tears of a Clown”), Bobby Bare (“Detroit City”), and Bobby Sherman (“Little Woman). Or maybe to that “Splish Splash” Bobby — Bobby Darin — who’d graduated to a more sophisticated sound, finding jazz and leaving teenybopper-dom behind with songs like “Mack the Knife.”I was enough of a theater nut to know that that particular song was from an off-Broadway show called The Threepenny Opera.
