520. Frankie Valli
Singer Frankie Valli was a band member of the legendary Four Seasons! Some of the band’s hit songs are “Sherry,” “Rag Doll,” and “Let’s Hang On.” In addition, Frankie Valli recorded a terrific tune, “Grease,” which is also the name of the classic 1978 movie. So, my 520th video features a Frankie Valli performance.
