Wow! Thank you all so much for the suggestions!

I'd also seen the song "Blessing" on one of her CDs, downloaded it, and was disappointed. But I'll let you know as soon as /if I have any success with either her agent or record company. Not sure how to approach the Prarie Home Companion angle. I'm sure it is the case that she performed this song on the air and that it wasn't in her "repertoire."

Thanks again. This is such a great site. I was dazzled when I found it!
