Des McAnuff (The Who's Tommy, Big River) directs the story of American pop group The Four Seasons — the highs, the lows and all in between — which comes to life in the musical Jersey Boys with the help of their hits "Sherry," "Big Girls Don't Cry," "Walk Like A Man," "December 1963 (Oh, What A Night)" and more. The show began on Broadway Oct. 4, 2005 and opened at the August Wilson Theatre Nov. 6.

The forthcoming national tour will launch from San Francisco's Curran Theatre (starting Dec. 1) and is also scheduled to stop at Los Angeles' Ahmanson Theatre (May 2007) before heading to Chicago's LaSalle Bank Theatre in October 2007.

Jersey Boys features music by Bob Gaudio, lyrics by Bob Crewe, and a book by Marshall Brickman & Rick Elice. The production garnered four Tony Award wins for stars John Lloyd Young and Christian Hoff, lighting designer Howell Binkley and for the top prize Best Musical.

Young (The Drawer Boy, The Chosen at Paper Mill) joined the cast for the Broadway run. Original stars Hoff (The Who's Tommy), Daniel Reichard (Radiant Baby, The Thing About Men) and J. Robert Spencer (Side Show, Lucky Duck) reprise their roles from the La Jolla Playhouse world premiere.
