Idina’s Defying Gravity in the OBC. When I knew nothing about the show apart from it was something to do with the Wizard of Oz. It blew me out to my seat which was probably about 10 rows back from the front.
One Day More the first time at the excellent sit down production of Les Mis in the early 1990s in Manchester. Again I didn’t know the music or the story and it cemented my love of musical theater.
