Buffy Sainte-Marie and Mari Boine

I'm not really familiar with Buffy Sainte-Marie, but every once in a while she pops up doing a version of a song I'm fond of ('Song of the French Partisan' being one, and I just found she did a rather alarming 'Lyke Wake Dirge').   Plus, if I'm to understand right, she originally wrote 'Eagle Man, Changing Woman,'  which is covered by a favorite artist of mine, Mari Boine.

'Eagle Man ~ Changing Woman'  by Buffy Sainte-Marie.

'Goaskinviellja [Eagle Brother]' by Mari Boine, since I couldn't find her rendition of the above song on youtube.
