Something that popped in my head as we were waiting for Alabama 3 to start, was offering the gig as a product. 

Imagine recording the concert live onto MP3, straight from the mixing desk.  Then you could copy the MP3 onto cheap, low storage USB memory keys for selling to people as they leave the venue. 

USB keys are pretty cheap these days and if you add on a pound or two for making a profit, you’ve got a nice little money making scheme, and a cheap way of promoting your band.

Or am I being daft?
