So, you want to help on a show? You want to help backstage on the Crew with Props etc. So before learning the skills required, we need to look at some essentials so that do not stand out. Well the first thing to think about it what to wear. Black is the correct outfit if you are appearing on stage moving props and set even during an interval or blackout. Another skill is not to speak loudly in the wings etc whilst the show is happening. Use a torch not your phone if needed, preferably with a bit of blue gel on the front. Rehearse all the crew actions, get it nice and slick whilst moving stuff on and off stage. If it runs smoothly and slickly the Audience will accept it, even when done in full view. Likewise, don’t be seen by the audience peeking out at that them to see who has arrived. Also do not say hello to friends in the audience as you change the set or props, just get on with your tasks. The cast is relying on you to get everything in the right place every night. If you get distracted and do something differently you are going to possibly put the cast offside. These basic things are important, and you need to know them before you start to learn a whole range of tasks that are important for the tech side of the show. Recently I have seen transgressions of these simple ideas, it can be as exasperating. Nearly as bad as the audience using phones during a show.
