purchase [Traffic: John Barleycorn]
If you go way back into the SMM archives, you can see several posts about John Barleycorn - the song must be the first one that comes to mind about harvest and such.
Sad to say, back in those days, the Internet was a different beast: most SMM bloggers had side accounts at hosting sites and placed their music files there to share wi. But that all ended a while back. As a result, if you do locate those posts, the music is not available, and so, for that reason, an update. http://sixsongs.blogspot.com.tr/2009/09/autumn-and-harvest-john-barleycorn-must.html
My post is a version by the author himself, in the raw so to speak. the essence of the song. And it's good.
However: http://sixsongs.blogspot.com.tr/2014/07/john-barleycorn-reprise.html appears to still be a good link.
