Shot from the Sonora Celtic Fair (previously the Calaveras Celtic Faire). This is the group "The Wicked Tinkers." Very high energy. Also, in my mind, a Teriyaki Donut? Why. Besides playing Celtic music and originals, they play Celtic music with a didgeridoo. That's what the guy with the blue handprint on his face is playing.
For those who don't know, a didgeridoo is an instrument invented and used mostly by the Indigenous people of Australia, folks who are most definitely not Celtic. So how does a didgeridoo get introduced into a Celtic band? In this case, it's probably because it just sounds cool, but it's possible it was adopted by the early settlers of Australia, most of whom were Irish and Scottish.
You have to remember that Australia originally was a British Penal colony. In fact, there's a really old joke about it. "Q: What's another name for an Australian? A: An Irishman who got caught." That's the joke. Anyway, it's possible that the Irish who were sent to the island and then settled there after being released from prison adopted the didgeridoo as a substitute for the bagpipes in Celtic music.
This group, of course, also has added a very distinct American rock tone to its music as well, thus further adding to its Teriyaki Donut status in my mind.
