The Hodag Country Festival, founded in 1978, is an outdoor music festival held each summer in Rhinelander, in Oneida County, Wisconsin, United States.
 The first festival, held August 4–6, 1978, featured Freddy Fender and Jana Jae and had an attendance of about 500.
 It is named for the folkloric Hodag, first reported to exist in 1893 in Rhinelander.
Charlie Piggott (born 14 July 1948) is an Irish traditional musician, best known as a founding member of De Dannan and has toured extensively in Europe, Canada, and the US.
 He grew up playing music in County Cork, where his first instrument was the button accordion.
 In the early 1970s Piggott played banjo in sessions at Galway's Cellar Bar with Frankie Gavin (fiddle), Alec Finn (bouzouki) and Johnnie "Ringo" McDonagh (bodhrán).
 In 1973, the group Dé Dannan was formed from sessions at Tigh Hughes, An Spidéal, Co.
 Galway.
 Piggott plays in the old style and many of his seminal recordings have caused him to be hailed as "one of the most influential Irish banjoists of the generation", but after damaging his index finger in an accident on tour he reverted to playing the melodeon.
 In 1976, he was a featured artist of the Smithsonian Institution, at the Festival of American Folk Life, for the American bicentennial.
 Today he plays a Black Dot Hohner Double-Ray, tuned C#/D. Piggott has revived many rare traditional melodies and has a reputation for performing them in accordance with the ethos of older players who have passed the music on.
