Dear Kim,  I have a listing of a great number of cobs, with titles.  
I can send you a photocopy, if you like.

The best way to identify cobs you're unsure of, is to invite over some
older folks and entertain everyone with a game of "name that tune".  
They may not be able to identify them all, but you'll have a grand time
doing it!

BTW, I don't believe I heard back from you about trading cobs.  Did you
receive my message?
