Oh, and at the same time - and often on the same square foot of stage with the clashing of ladders, lifts, buckets and whatnot - the actors, director, producers, light and sound and costume and prop designers, techs and stage hands, stage manager, interns, and volunteers are all equally busy. Not on the set alone, but on the Whole Show.
Tons o' Work! By Tons o' People!
