Just be grateful it's only angels' skirts I'm looking up. Anyway, I've got the reputation - just need a bit of angel action to confirm it.

As to the production, I'm sure the production design will be in the Glyndebourne archive. I was tempted to contact Julia Aries, the archivist, but had a sudden thought that the Angel might be an illegal immigrant, without ticket-of-leave from the opera house... didn't want to give the game away... :-)
