Just to augment a brilliant (as always) performance, the song was written in 1913, seven years before the Twenties began to roar! Otherwise, no notes (save the ones you guys sing...)
Craig Ventresco gives a crash course in every great mandolin style of the last 100 years in just a few tunes at this concert. It's like he studied all the best mandolin players of the 20th Century and absorbed everything they did, then made it into his own. In this tune he sounds like he's mostly channeling Yank Rachel.
