The AVO Session, Basel is a Swiss music festival; from the details at
http://www.avo.ch, it appears that AVO makes cigars.
There is a merchandise link in the website, but nothing BF-related. I have his AVO concert DVD myself and it's pretty good quality; not a wobbly, hand-held camcorder effort from the audience!
I'll make a few enquiries on behalf of Oberon; anyone else interested (the supplier isn't UK based, so I'd prefer to keep it to one order to keep the costs down, if there's any left)? DVD is region 0, by the way, so should hopefully play everywhere.
If the cost is off-putting, I'm always interested Roxy & BF part-exchanges, so maybe you have other live shows on DVD or CD to offer?
