While they aren't a band of brothers, Mumford & Sons covered The Avett Brothers' “Go to Sleep” as if they were one big happy family. Bringing in help from opening band Cadillac Sky, the whole collective jammed on stage with no shortage of banjos. As a good family should, they all took turns with various vocal and instrumental solos.
The high point of the cover came when they took to the floor for a quick nap while the audience took over. Soon after, they arose with more energy and dancing to bring it all home. Though they hail from England, Mumford & Sons had no trouble channeling the southern vibe that the Avett Brothers project so well. If I didn't know any better, I'd say that Mumford & Sons and the Avett boys were all in the same family after all.
