LET’S Hang On takes a musical journey through the career of Frankie Valli & The Four Seasons at the Grand Opera House, York, tomorrow at 7.30pm.

Dino Buttarazzi, Martin Peat, Scott Walker and Jay Harrison take the Four Seasons’ roles while Robin Maughan scales the falsetto heights set by Valli in a nostalgic night of Frankie favourites, such as Sherry, Bye Bye Baby, Walk Like A Man, Rag Doll, Can’t Take My Eyes Off You, Working My Way Back To You and Big Girls Don’t Cry. December, 1963 (Oh, What A Night) and Grease are the peaks of the later Valli years and the show climaxes with the title number.

Maughan and co performed at the Royal Albert Hall for Frankie Valli himself last year when the New Jersey singer told them: “You guys are dynamite.”
