Where can I find a guitar tab or chords for the version of Barbara Allen played in Dark of the Moon?

I was just asked to play this on my guitar for the school play. I looked everywhere for a tab or chords or even a video of how to play it but I can’t find it anywhere. I can only find the older version that is not in the play but that is not what I need.
Hope someone can help…
Thanks!
