I think I heard the Peter, Paul and Mary version first. Their harmonizing made it almost as good as the original. Waylon does a nice cover as does Johnny. Pretty hard to screw up such a good song mind you.
That would be a good one to see, but not in her repertoire yet. These 2 she does will definitely get you pumped (and I love how her parents have her foot pedal action
isolated in the corner to see how really in tune/good she is)...
