"Billy Boys", also titled "The Billy Boys",[1] is a loyalist song from Glasgow, sung to the tune of "Marching Through Georgia."[1] It originated in the 1920s as the signature song of one of the Glasgow razor gangs led by Billy Fullerton[2] and later became viewed to reflect the long-running sectarian religious hatred directed by some Protestants against Catholics in the city. It is associated in particular with Rangers F.C.
