Thanks for posting this. It is rare to see a bluegrass musician play a ukulele. At some bluegrass jams that I have attended, ukuleles were frowned upon. If Dan Tyminski can play a ukulele, then I shouldn't be ashamed to bring one to my jam group
Did you know that ukuleles were used in the early 20th century by country music musicians? Early recordings known as "the Bristol Sessions" featured a ukulele on some songs. I found this out when I visited the Museum of the Birthplace of Country Music in Bristol, VA.
