It's great that so much material is available on youtube- just hope that there's some way young folk can steer through the vast amount of dross to find some of the gems which ARE certainly there.
Still no substitute for the real thing of course, which we old fogies were lucky enough to experience mainly through the 'revival'

On the subject of the nature of tradition, I have my own views but don't want to provoke any acrimony from the usual suspects.

However I've just read a lovely travel/history book called 'Love of Country- A Hebridean Journey' by Madeleine Bunting.

In it, she writes of the time 20 years ago when a superquarry was to be inflicted on the lovely Isle of Harris. This was to be used for roadstone in the Leicester area!! A quarry on such a huge scale would never be allowed in England- the company's argument was that it was a very remote area & even quoted Sir Walter Scott's journal as evidence of its meagre cultural value, with high, sterile hills...
I have never seen anything more unpropitious' Scott wrote from a boat offshore - he never landed!

   The company's case provoked a discussion about the nature of culture and tradition and the objectors' campaign relied heavily on two Gaelic concepts to explain the islanders' understanding of the value of PLACE.   'Duthchas' expresses the collective right to the land of those who use it, and 'corachean' being the belief that people BELONG to the land.
In other words, the future for Harris should be based on the use (but not destruction) of the land- fishing, crofting & tourism, and the plans were defeated, and a later plan for 234 wind turbines for the Isle of Lewis failed for similar reasons.
Anyway, one resident summed it up WITH NO REFERENCE to music..

'Another reality prevails in Harris- language, culture, history- the whole of everyday life- are embedded in tradition, not consumption. Tradition should not be confused with the past; it could better be described as the meaning of the past, distilled into the present and cared for, with a view to handing it on to future'.

   I've never heard it better expressed and as part of a wider culture, I could find little fault with that definition & just wonder if the 'folk revival' lives up to those standards?
