The musical will be directed by Joe Fredericks with musical direction and arrangements by Oliver Jackson and choreography by Sam Spencer-Lane. It is produced by Fredericks and Holly Reiss for MokitaGrit Productions and Danielle Tarento, in association with Southwark Playhouse. It is the first musical to be performed at the venue since it was founded in 1993.

According to press materials, the production will embrace "the aesthetic and ambience of the venue's location in the vaults beneath London Bridge Station to create an intimate production with a New York warehouse feel."

Young's previous theatre credits include appearances at the National Theatre in Afterlife and Never So Good and at the Oepn Air Theatre, Regent's Park in Cymbeline, Twelfth Night and H.M.S Pinafore. His TV credits include playing Sir Leon in "Merlin" and Marc Arlington in "Shameless."

McCarthy was recently seen as Velma Von Tussle in Hairspray at the West End's Shaftesbury Theatre and the title role of The Drowsy Chaperone at the fringe Upstairs at the Gatehouse. She created the role of Donna in the original London production of Mamma Mia!, for which she was Olivier-nominated; other roles include playing the Nurse in Medea opposite Fiona Shaw, in London and on Broadway, Mrs Johnstone in Blood Brothers, Fantine in Les Miserables, Florence in Chess and the title role of Evita. TV credits include playing Roisin in "Bad Girls" and Jane O'Brien in "Law & Order." Fredericks has previously directed A Christmas Carol at the King's Head, Pages: Promised Land at the Union Theatre and Songs for a New World (Upstairs at the Gatehouse). He was an associate director on Once Upon A Time at the Adelphi at the Liverpool Playhouse (also The Union Theatre 2010 production), which won the T.M.A. Award for Best Musical, and was also an associate director for the 2006 season at the Scoop, the outdoor theatre next to London's City Hall, for whom he also composed and acted as a musical director.
