Sorry, but it is a Brit musical - I should know - I was there on opening night at the Barbican Centre in London. The music was written by a French composer, lyrics were always in English. It starred Patti Lupone and dragged on for hours. I could not leave because Princess Margaret was drinking in the lobby (smart lady!) and security would not let us leave the building. It was produced by the Royal Shakespeare Company of Great Britain.
Saw it in London too, though not opening night. Absolutely loved it - have the CD, DVD, and can’t wait to see the movie.
