Here is a little four-part documentary about when Les Misérables first transferred across the pond to Broadway. There are some clips of the OLC and some adorable images of the cast members very, very young.
Like Anthony Crivello with an afro, Colm Wilkinson with brown hair, Frances Ruffelle looking about my
age, Terrence Mann with his curly shoulder-length black hair (and looking very much like a young Tim Curry) and a slim little Michael Ball also with curly shoulder-length hair.
This is part one. Just go to the next three parts from there... they're not exactly hard to find.
I am playing the Queen of France right now in a play. Try not to decapitate me.
