That's what I've been thinking, Charley. The problems with recording "through the air" are that a) the sound can be clear or mushy depending on where your input mic is in relation to the speaker(s)* and b) ambient noise - including the audience singing along, chairs scooting, papers rustling - gets picked up too.   In fact, ideally, the camcorder or laptop that is recording the video would have a direct audio line in from the sound board's pre-amp.   That way no one would have to fiddle with the sync between the audio and video.

As for monitoring the recorder, video-wise, I don't know how feasible it is to monitor the audio input on hand-held camcorders or on laptops with built-in camcorders.   It's easy to see what the video image will be like on a laptop because it's a WYSIWIG sort of thing; with a tripod mounted camcorder you'd have to sit or stand behind it, which might or might not block the view for some of the audience. Anyway, there should be a way to do this if TPTB at Getaway know decide in advance to try to have the concert recorded.

*I think the difference in general sound quality of my videos from 2008 and 2010 illustrate this. The mic (on the laptop) was positioned almost exactly the same, in relation to the performers, both years, but the stage was configured differently, with the speakers much farther apart in 2008. I think I captured more of the sound of the live voices and instruments, relative to the amplified sound, in 2008 because the speakers were farther away.
