Some good guesses, but, no, last week’s Regie quiz was neither Ariadne auf Naxos nor Auntie Mame, but rather that faded valentine that the occasional opera buff years to see revived: Thomas’ Mignon. (That blonde was, obviously Titania.) The staging was done for the Buxton Festival by Annilese Miskimmon.
And and now for something completely Regie.
Remember, cher public: if you recognize the production, hush!
