Here is one of the commercials that Channel 4 WSMV in Nashville is currently airing. They recorded me playing the Snowbird song while sitting on the porch of the Musical Heritage Center of Middle Tennessee at sunset. Sharon and I were there for the monthly celtic session last October.
When the videographer arrived everybody at the session learned the tune and we played it about a dozen times, each time through it was a little different. Great bunch of musicians, everyone listening and adapting to what the others were doing with the tune.
