Six the Musical was created by Toby Marlow and Lucy Moss and first performed at the Edinburgh Fringe in 2017, retelling the lives of Henry VIII's six wives as a pop concert. Katherine Howard, the fifth wife, performs All You Wanna Do as a seemingly upbeat pop number that gradually reveals a darker story. Clips of her standout lines spread widely through theatre fancams, cast recordings and social edits, and this confident lyric became a favourite shorthand for fans celebrating the character's stage presence and unapologetic attitude online.
