At the centre of the new show is the music of a man whose high-pitched voice has brought countless world hits to the eternal pop repertoire: Frankie Valli. With his band The Four Seasons, he celebrated hits such as "The Sun Ain't Gonna Shine Anymore", "Bye Bye Baby (Baby Goodbye)", "Can't Take My Eyes Off You" and "Grease". The four-member cast offers a best-of programme today.
