I mostly use  Google Advanced Search

There is a reasonably comprehensive set of links to other examples here and elsewhere in this thread:  Penguin: John Barleycorn

I'll add a link to this thread.  It's puzzling that Sing Out should say "Scotland and Ireland, as well as in England"; where John Barleycorn is concerned, "England and Scotland, as well as in Ireland" would have been more accurate.

A midi would be good; you could send it in the first instance to Alan of Oz for the  Mudcat Midi Pages.
