Aragon Mill was beautifully done by Andy Irvine on one of Patrick Street's albums.

At least 20 years ago we had a bloke with a didgeridoo at our somewhat anarchic "sessions" at the Wellington in Boscastle. He was quite well-behaved, diffident even, and provided a pretty fair, very low drone for tunes in D. There's a busker in the underpass in Truro who intersperses his didgeridoo playing with a sort of growling vocal, not quite in the style of "Lost John" by Sonny Terry. He has a vicious-looking dog and has been known to snarl sarcastically if you don't give him a bob or two. Not exactly charm incorporated...
