I have been asked to do historical performances and need to find dates on when tunes were first written. If all I can find is what years a tune was most popular, I could go by that also. Can anyone help me with this? Is there a web site I can go to that will list the year the tune was popular along with a search data base? If you could reply to me at kerry@GilaMountainDulcimers.com I would appreciate it.
