030.
OK, everyone. May I please have your attention? I'm Bill Smith, the director of the school play for this year. It's a great pleasure to have you as assistants to help organize the play. I'm sending around a form for you to put down some information on how we can get in touch with you, so please put your names and phone numbers down. Also please write down the performances that you will be able to help with. I realize that not everyone can come to each performance, but the more you attend, the better. However, you should also keep in mind that we will need a lot of time, and we may end up staying quite late into the evening.
If you have any special skills, it would be good for you to write those down on the paper as well. In particular, we need two lighting and sound people. We have hired one full-time lighting man, but one person can't do everything. We need several people to help out setting up the lights.
Once you have all marked down any special skills you might have to offer, please return the form to me. At our next meeting on Tuesday, we'll begin talking about all the different jobs. While you're waiting for the sheet to get passed around, I'll be happy to answer any questions that you have today.
