Susan,
Time will be the biggest problem but I have the inclination, the 5 volumes of Child Ballads, the abridged version of Bronson and the means to provide MIDIs of the tunes.

I can easily find the Child ballads that are in the DT (but not in numerical order) but it's not so easy to list the ones that are NOT yet in the DT. Can you help in any way with such a list.?

Cheers,
Alan
