Bravo! What a great schtick. Don't kid yourselves. Those are not hayseed, plowboys. That is a legit bluegrass combo who came up with an excellent idea to actually make money at their craft. I gotta tell you, I've worked with a bunch of bluegrass acts and they are some of the most incredible musicians on the planet.
The banjo picker isn't using thumb and finger picks but using a guitar pick. Looks to me like he's a guitar player that's playing the banjo. This isn't Bluegrass at all and I'm sure Tom T. Hall would agree with me. A fun video nonetheless.
