Joe, it is our intention at the Lewes Favourites and, I'm sure, Steve's at LeSession to promote traditional music as best we can and provide free access to our resources. The confusingly similarly named The Session does similar work. I am sure there are many others. Producing and distributing a tune book and running a folk club cost money. We cannot afford to give away the tune book and any attempt to undermine its commercial viability does us serious damage. None of us are making any money for ourselves.
It was Pat Turner's stated aim to run a commercial website. In his future plans he says "You no longer have to buy a commercial collection, just to get hold of the few tunes you want.". In other words, his intention was to take resources that were being given away for free, repackage them and sell them.
Fortunately, he seems to have seen the error of his ways.
