Legendary singer Frankie Valli took time out from his sold-out concert tour this week to meet the casts of both UK productions of the smash-hit musical Jersey Boys, which tells the true-life story of Frankie’s rise to fame along with his band The Four Seasons. Frankie joined the UK and Ireland Tour cast in Manchester as they performed an excerpt from the show on BBC Breakfast, and visited the London show at the Piccadilly Theatre before going onstage to meet the cast and crew.
