The Flamingos

Beginning in 1951, Chicago vocal group the Flamingos presaged the Doo-Wop era by several years. Best known for their smooth, sophisticated harmonies and lush orchestration, the group struck gold in 1959 with the crossover hit "I Only Have Eyes for You," a song younger listeners may recognize for its constant use in various television commercials over the years. Amazingly, the group scored chart hits until 1970, and to this day they remain a favorite of vocal group aficionados.
