I'm delighted that this one has taken off and thanks to all those who have contributed to my future insomnia!
Actually for my tuppence worth, since someone has already mentioned Radio Scotland, there are a couple of distant ones I often listen to.
There's Radio Newfoundland which plays all Newfie artists.
There's a programme on 3RRR in Melbourne which is called Old Folk Show which goes out on 4 am GMT on Tuesdays. Finally there's Rod Mackie's "Sweet Music" (good old fasioned Nova Scotian music) on GKEC and goes out at 10 PM gmt -all on the net.
