Take a torch!! I recently filmed a gig in a 200 capacity venue and forgot just how dark everything is at the back of the room. It was a nightmare trying to find tapes, batteries and even some of the controls on the camera.

I would also suggest taping the Cam1 tripod to the floor to stop it being knocked by the audience.

If possible have someone monitoring the recording you are taking from the mixing desk - maybe record on to minidisc but don't rely on the sound engineer to change the discs when they run out.

Also try to synch all 3 cameras using a flashbulb from a stills camera - this will make things a lot easier when you're editing (if you do this, it's important to keep all the cameras rolling throughout the performance).

Good luck. I'm sure you'll do great.
