This isn't very clear. Do I understand correctly that you have a tape copy of an album, and you can't identify the album or the performer(s)? Or did the tape come from a live performance?

Please try again. Quote a line or so from each song. Give us the exact words if possible. Make it clear whether your quotes come from the same song or different songs, etc. Describe the performance: male voice, female voice, several voices? What instruments? Are the songs all Irish? It's likely we can help if you give us more information.
