Hi David,Here is the link to your
sample number 10http://people.A2000.nl/dfernand/Samples/SAMPLE10.mp3
I listened to it, but it doesn't sound at all familiar to me. The only thing I can hear is that the singer possibly has a language other than English as his first language, that is that he seems to have a strong accent. So he may not necessarily be English, Irish or American.
Good luck with your search. Wait for some other Mudcatters to listen to it and you might get the answer.
