Nina Simone - Revolution

Awesome song and performance!
it gets cut off, and i can't find another video of it, but it's worth it so i leave it.
I attach here also the studio version.
Call me crazy, but it does somehow here and there resemble the Beatles song by the same title, but alas it is different, and fully worked up by Ms. Simone so... respect!
