Hidden gems

Things I take for granted - like the fact that as a member of staff on the worlds longest running show, I am privileged enough to have access to a piece of history every day.
This is the "wind machine" operated every night for the show. Peter Saunders was the original producer who worked alongside Agatha Christie when the production first opened and until very recently it was the only method of a "wind" sound effect used.
It is still in use today, in the shows 60th year.
