THere is a record called the SInging Men of Ulster, (Innisfree - Green Linnet S1F1005) has some Liam Andrews, and is likely out of print, but e-mail Wendy Newton at Green Linnit and ask, who knows, maybe she can make you a tape or something. They must have a web site at this point. Anyone know a URL for one?
Much better to get you music from her than Ian P.
All the best
