The Platters are so smooth you don't realized you're being doo-wopped. Along with the Moonglows and the Orioles and others, they were amongst the smoothest purveyors of the beloved vocalizing style. They eloquently employed the technique on the unforgettable "Twilight Time," "It's Raining Outside," "Try a Little Tenderness," and "My Old Flame." Another song, "I'll Take You Home Again Kathleen," is a story in itself. The title is surprisingly popular with songwriters.
