They lived in the south-west of Ireland, around the Cork / Kerry area. Funnily enough, Aberdeen City library had the CD as well, and I think I still have a few tracks on a cassette tape. Here's what I remember - and it must be at least 15 years later. The fiddler was male and had grey hair and a beard. The bodhran player was a lady with a German-sounding name. The uilleann piper was female. Does that help ?
Probably not, but I can still see the faces in my mind's eye from the CD insert. I did try to find a bit more about them a few years ago, but drew a blank. I'm going to Co. Cork for a musical event in about 6 weeks time. I'll make a few enquiries then. I'll try to find the tracks I recorded, but think I only kept a few - certainly "The Sister's Reel", and also the last track of reels.
