There has been a video of an acoustic version of AIG in the treasure chest that is the BBC's Folk Awards website for more than a fortnight. It's the performance they did at The Brewery on the night. There are several "acoustic" versions of it on YouTube from various Disheveled Duo + 1 gigs played across the Devonian Main over the last 12 months. If you've only heard the "pop" version up 'till now you haven't been seriously looking.
