Joe - I don't remember where I found it, but out there is a text file (ascii delimited) of child's ballads. thorugh 305 C I believe.it was well over 2500 pages when I started work on it. (I haven't gotten very far) in Word, 1A thorugh 10Y is 48 pages, double columned. I have that as a seperate file.
I don't vouch for the accuracy of the transcription as I have no idea who did it. all I know is it had to be an incredible amount of work.
