I play this in G with the fiddle cross-tuned GDgd. I first learned to play this from a live recording of Alan Jabbour and Bertram Levy. They are pretty much the same melody. http://dla.acaweb.org/cdm/singleitem/collection/Warren/id/1894/rec/1 ...but, like so many other tunes I learned first, when I moved to Memphis and played what I knew with the locals – I learned that there is another version. And I looked to find a recording of the other version that I wanted to learn. I really don&#39t know who&#39s version I ended up learning. It might be just what I picked up from the locals. But it favors what I perceive to be the older, more traditional version from the civil war era. This one I listened to: https://www.youtube.com/watch?v=gRXzBGPyJXc There are 2 entries at Fiddler&#39s Companion: http://www.ibiblio.org/fiddlers/JOHAN_JOHN.htm There are 2 audio files at DLA: http://dla.acaweb.org/cdm/search/searchterm/john%20brown&#39s%20march/order/nosort and Slippery-Hill has one: https://www.slippery-hill.com/search-page?search_api_views_fulltext=john+brown%27s+march&=Search
