Leo Kottke gave it a bit of a face-lift:
Here we have a old clip of young Leo playing it with Chet Atkins and Doc Watson. We can see that neither Doc nor Chet know the tune, so they're learning it as Leo plays it. We can also see Chet spending the first minute or so tuning. And he doesn't make a move until he's got it right. There's some lovely interplay here between the two great masters and the talented youngster.
And finally, here's a newer clip of Leo playing it live, and even improvising a bit (following a typicallly humorous introduction):
They're not making 'em like Leo anymore. I hope he lives another couple hundred years.
