Six (stylised in all uppercase) is a British musical comedy with book, music, and lyrics by Toby Marlow and Lucy Moss. The musical is a modern retelling of the lives of the six wives of Henry VIII presented as a pop concert, as the Queens take turns singing and telling their story to see who suffered the most due to Henry and should, therefore, become the group's lead singer. The musical was first presented by Cambridge University students at the Edinburgh Festival Fringe in 2017. It has since gone on to professional productions in the West End, on Broadway and internationally.
