Hey Mr or Ms Grouse, don't grouse!
If you type "Kelso free Folk festival" into Google you get the homepage:
http://www.kelso.bordernet.co.uk/news/folk-club/16.html and a nice news article with a link to the programme from here http://www.tradmusic.com/newspage.asp?newsID=430

Just to save you the bother of clicking, it's September 5th - 7th.
