!5 minute changeover, good luck.

Just enough time to don cagoule and over-trousers.
Jokes to one side, one of the bands I play with do a lot of community and charity events. Some outdoor, some indoor. It's my experience that a lot of the organisers, who are usually lovely and committed people, often have no real idea about what's involved in putting on a band. If possible, you need to communicate early and tell them, 'right, this is what we need....etc'. I've often found the organisers are relieved that someone in the know can help them make it happen. A win-win. I wish I'd got a tenner for every time one of them has said 'Oh yeah, I hadn't thought of that'.
A current example, I'm liaising with the organiser of an indoor fundraising event where we are to play a quiet set whilst other things are happening. I've persuaded the lady that we really need to be as close to a power-source as possible. It's for a charity supporting the independently-living sight impaired community. She just hadn't realised that we might have trailing cables. I'd prefer a better way to get in the papers!
