Catch some blackbird's wing

I came across this video of Dave Matthews and Emmylou Harris singing Gulf Coast Highway (they don't actually start singing till about 1:30). I do love this song. And here is the original from Nanci Griffith, which is every bit as good and gloriously 1980s Texas. (And of course one thing lead to another on Youtube, and I found this, which is beautiful, and then you can listen to this duo sing Long Black Veil, or an older version with Johnny Cash and Joni Mitchell.)
