Sounds like our postal service!
Sorry, I've already retreated from 'folk' - you'll all have to put up a better argument than those so far if I'm going to retreat from 'Traditional'.
Aren't we being somewhat exclusive here by assuming that everybody has access to computers and the Internet. Here in the West of Ireland, which had a thriving tradition up to three or four decades ago............... but I'm sure you don't want to know that.
PRS member - I do wish you'd desist from hanging a price tag on what, by definition, is common property - it's like living through The Enclosures again.
The much demonised MacColl put many hundreds of traditional songs and ballads back into circulation and NEVER, NEVER, NEVER at any stage attempted to copyright them. Most of the time, with one exception (First Time Ever - not one of his best) he didn't even bother too much about his own compositions, but was pleased and proud to have them sung. One result of the money that came from F.T.E. was Blackthorn Records, which gave us, among other things, probably the definitive collection of traditional ballads, Blood and Roses.
