De Dannan
De Dannan (originally "Dé Danann") is an Irish folk music group.
It was formed by Frankie Gavin (fiddle), Alec Finn (guitar, bouzouki), Johnny "Ringo" McDonagh (bodhrán) and Charlie Piggott (banjo) as a result of sessions in Hughes's Pub in An Spidéal, County Galway, with Dolores Keane (vocals) subsequently being invited to join the band.
The fiddler Mickey Finn (1951–1987) is also acknowledged to have been a founder member.
The band was named after the legendary Irish tribe Tuatha Dé Danann.
In 1985 the spelling of the name was changed from "Dé Danann" to "De Dannan" for reasons that have never been made clear.
Since 2010, however, Finn and McDonagh have recorded and performed with a line-up named "De Danann", and, since 2012, Gavin has recorded and performed with another line-up named "De Dannan".
