We found a video of 2013 SPBGMA International Bluegrass Band Championship, The Meyer Bluegrass Band, performing one of the songs that led to them taking the trophy on Sunday afternoon.
The Missouri band consists of siblings John Meyer on banjo, David Meyer on guitar, Mary Meyer on mandolin, and Jimmy Meyer on bass.
Here they are at SPBGMA, performing one of several Lonesome River band songs they chose for the competition.
You can see more videos of their SPBGMA performances on YouTube.
