Clyde McPhatter was one of the most influential R&B singers of the '50s and early '60s. In his own time, his name and voice loomed so much larger than that of the group the Drifters, which he founded, that it took five years for them to recover from his departure. McPhatter was idolized by Black audiences as few singers before or since ever were, and for almost 15 years helped define rhythm & blues and its transformation into soul. In a way, he was the most improbable of R&B stars, a gentle high tenor who, superficially at least, seemed more suited to the angelic strains of gospel music. And his name gave some potential managers and agents pause -- what kind of R&B singer, forget a star, was named Clyde? And Clyde McPhatter seemed like a backwoods burlesque of a Black American name. But when he sang, the doubts and the laughter all disappeared -- even on his live album from the Apollo Theater, recorded during his declining years, when he describes physical lust in the hit "Ta Ta," he makes it feel urgent and real, and utterly convincing.
