I met Mairéad Ní Mhaonaigh of Altan a couple of years ago in the company of an upcoming Irish Trad band. She advised them against signing to Green Linnet because of problems in getting them to pay up royalties which were due.
Clearly enough people are now owed enough money to make it worth their while going to law. Sad to see it happening with a label which seemed to be so good for trad music in the days when there were hardly any commercial recording opportunities for that sort of music.
