Countess, you may be able to download a manual from the manufacturer's website.
Murray - I hate country! Of your list of wonderfuls, I'd listen to Kottke (but not for long) and Guillory.
The best I've seen at Cambridge - might have been Martin Carthy and Norma Waterson. Then of course there was the year that Anglia TV recorded and broadcast the 4-piece (performing on the campsite) of Roger the Chorister with Rachel (me, Jacqui, our daughter Rachel and Royston Ford) - grin!
The worst - the year the club tent walked out on the then best living squeezer in the country, a certain Fitzpatrick, possibly the rantings of John Cooper-Clarke, maybe the german bikers who wanted to rape my step-daughter.
