Sorry I feel I have tp put this right:

I remember Willie Scott the Border Shepherd singing a spoof of the Banks of Loch Lomond. Fred Jordan (deepest appologies)not Wedlock song all sorts of stuff.

Didn't Hamish Henderson collect one of his own songs (The Freedom come all ye) from Jeanie Robertson?

The tradition is alive and we can contribute just by singing and playing.

And further

I find the term traditional more useful than folk because I think we can agree with what Greg suggested and be fascinated by songs and tunes that have survived against all odds within oral traditions, sometimes passing in and out of print and sometimes going to other continents and coming back.

The problem I have is that sometimes something is declared traditional and given reverence and even a made up history, surely we must be suspicious of this kind of thing?
