well if they are not commercialy viable,if the owners of the recordings cared about passing on traditional music,.
allthey have to do is start a you tube account,put them up on youtube,and let people download them.-simple as that.
I have just put up three tracks from along deleted album,which features a beautiful concertina and clarinet duet,Iam not making a penny out of it,but I like sharing this music with others http://www.youtube.com/watch?v=ItcBocS_x_M http://www.youtube.com/watch?v=ItcBocS_x_M
