The Wild Rover is an English song. Luke Kelly learned it (maybe from Ewan MacColl) when he was doing the UK folk clubs. Luke took it back to Ireland around 1963/1964. Liam Clancy was a friend of Kelly and he introduced the song to the group.
There is a live recording from 1965 where Liam teaches the song to the audience. In Ireland too! And there is a video of The Clancys teaching it to Pete Seeger.
Hard to think there was a time when no-one knew The Wild Rover.....
Two pieces of Irish Folk Music - a freedom song and a prodigal son song - from a band which did much to popularize the genre in the '60s. There is nothing on the label to denote which was the 'A' side; I have listed 'Rising' as the 'A' because it has the lower matrix munber.
