Thanks Q for correcting the spelling error and darkdriver for the info. I have already located the 16 Gems book but it is not the one. It is a songbook that Bill produced years ago. Apparently there was a #1 & a #2. My friend already has #1 but wants to add #2 to his collection. He has a vast archive of older country & western material (bluegrass included), so if he does not have this book it is probably rather hard to come by.
Thanks again,
