Great stuffI think that there is a link between the Corries and the Dubliners. It is one of the period of which they were/are playing and the fact that in that time they both had a degree of commercial sucess.
Which is probably the main reason why the Corries are not "taken seriously". at least on the UK side of the pond. Here to 'suceed' in producing folk music that is popular is probably the worst possible crime.
The same can also be said for Ralph McTell, who despite still producing great songs and being one of the best 'Ragtime' and blues guitar players I have seen, has never been forgiven, by some for the sucess of 'Streets Of London.
