Bumping in to The Playhouse in Edinburgh .............. late 70's/early 80's. "What's this Elfin Safety you speak of?"
that's a hell of a loading bay/dock! My mate was the manager of the playhouse and kings theatres a few years ago.
there was a theatre in Grimsby that you had to climb and run along the grid gantry to grab the lines and 'float'/ jump down to bring the flys out! fly floors were always the best places
