I did not mention it because I dont think about it, i sing in my natural voice, here
http://www.youtube.com/watch?v=-jCTeQdBFP8, I have been singing like this since 1976 and playing folk clubs all over the british isles for 35 years[and it dont seem a say too long], however academics would call me a singer of traditional songs not a traditional singer, PERSONALLY I JUST SING THE SONGS AND ENJOY THEM AND IGNORE PEOPLE LIKE THAT.
Happy New Year to Jim Carroll
