There! Less than TWO seconds and a search of the Mudcat gives about a dozen threads, and a couple of songs and the tune in MIDI format.Less than FIVE seconds of scanning a SINGLE thread, came up with an abc of the tune. Now, there are FREE programs, like iABC, with which you can display the sheet music from the abc file.
So searching Mudcat is pretty easy. All you have to do is locate the BOX at the top right corner of the main page that says, Lyric and Knowledge Search. Enter in Ashokan, and in less than two seconds more information than you thought you ever wanted is available. And most of it is pretty good and informative.
