Óró Sé do Bheatha Bhaile is a traditional Irish song that is also associated with the Jacobite uprising at Culloden where mentions of Séarlas Óg ("Young Charles" in Irish) were added referring to Bonnie Prince Charlie.
In the early 20th century it received new verses by the nationalist poet Padraig Pearse and was often sung by members of the Irish Volunteers during the Easter Rising. It was also sung as a fast march during the Irish War of Independence.
Seo Linn is an Irish folk-pop band that promotes the Irish language. I love their version of this song.
