Frankie Valli at Borgata

With its intricate vocal harmonies and doo-wop approach, The Four Seasons became one of the most successful groups of the 1960s. Lead singer Frankie Valli's signature falsetto became the trademark of the group. Valli, 79, performs tonight and Saturday in The Music Box at Borgata Hotel Casino & Spa in Atlantic City.
