Seems they recycled quite a few of the songs over the years. I presume 'Marienne's Song' and 'Marianna's' are one and the same.

I also remember singing 'Sourwood Mountain' and enjoying the 'Hey Diidy Ump' chorus. Checking my copy of Cecil Sharp's Appalachian song book it looks like it's right out of there, with a few alternative verses substituted.
