Frankie Valli

Pop singer Frankie Valli was permanently associated with the group for which he served as lead singer, The Four Seasons. But he also maintained a separate solo career during much of the band's tenure that included several major hits beginning with "Can't Take My Eyes Off You" and including "Grease." He also found work as a film and television actor. In general, Valli's solo recordings were closer to middle-of-the-road traditional pop than his work with The Four Seasons, and he abandoned his trademark falsetto when working under his own name alone. To a large extent, however, his name was interchangeable with that of the group, which was billed often as "Frankie Valli & The Four Seasons."
