Question: Name the loyalist song from Glasgow, sung to the tune of 'Marching Through Georgia' and a signature song for a razor gang led by Billy Fullerton which was involved in street fighting with a large Catholic sectarian street gang known as the Norman Conks?

<P0-S0> "Billy Boys", also titled "The Billy Boys", is a loyalist song from Glasgow, sung to the tune of "Marching Through Georgia." <P0-S1>  It originated in the 1930s as the signature song of one of the Glasgow razor gangs led by Billy Fullerton and later became viewed to reflect the long running sectarian divide in the city. <P0-S2>  It is associated in particular with Rangers F.C.. <SEP> <P1-S0> John Oliver Weir (born 1950) is an Ulster loyalist born in the Republic of Ireland. <P1-S1>  He served as an officer in Northern Ireland's Royal Ulster Constabulary's (RUC) Special Patrol Group (SPG) (a tactical reserve unit), and was a volunteer in the illegal Ulster Volunteer Force (UVF). <P1-S2>  As a member of the UVF's Mid-Ulster Brigade led by Robin "the Jackal" Jackson, Weir was a part of the Glenanne gang, a group of loyalist extremists that carried out sectarian attacks mainly in the County Armagh area in the mid-1970s. <P1-S3>  Along with his RUC colleague Billy McCaughey, Weir was convicted of the 1977 sectarian killing of Catholic chemist William Strathern and sentenced to life imprisonment. <P1-S4>  Weir's affidavit which implicated Jackson, other members of the Glenanne gang, soldiers of the Ulster Defence Regiment (UDR), and his colleagues in the RUC and SPG, in a series of sectarian attacks, including the Dublin and Monaghan bombings, was published in the 2003 Barron Report, the findings of an official investigation into the 1974 car bombings commissioned by Irish Supreme Court Justice Henry Barron. <SEP> <P2-S0> The Norman Conks (or Norman Conquerors) were a large Catholic sectarian street gang active in Glasgow. <P2-S1>  It was one of the popular Glasgow razor gangs, and was active from the 1880s to the 1960s, with its headquarters and most of their members based about the Catholic area of Norman Street in Bridgeton. <P2-S2>  They were initially a penny mob, but evolved into a larger, influential gang. <P2-S3>  They were often involved in street fighting with the Protestant Billy Boys of Bridgeton. <P2-S4>  The gang included girls. <SEP> <P3-S0> The Shankill Butchers was an Ulster loyalist gang—many of whom were members of the Ulster Volunteer Force (UVF)—that was active between 1975 and 1982 in Belfast, Northern Ireland. <P3-S1>  It was based in the Shankill area and was responsible for the deaths of at least 23 people, most of whom were killed in sectarian attacks. <P3-S2>  The gang was notorious for kidnapping and murdering random Catholic and suspected Catholic civilians; each was beaten ferociously and had his throat hacked with a butcher's knife. <P3-S3>  Some were also tortured and attacked with a hatchet. <P3-S4>  The gang also killed six Ulster Protestants over personal disputes, and two other Protestants mistaken for Catholics. <P3-S5>  Most of the gang were eventually caught and, in February 1979, received the longest combined prison sentences in United Kingdom legal history. <P3-S6>  However, gang leader Lenny Murphy and his two chief "lieutenants" escaped prosecution. <P3-S7>  Murphy was killed in November 1982 by the Provisional IRA, likely acting with loyalist paramilitaries who perceived him as a threat. <P3-S8>  The Butchers brought a new level of paramilitary violence to a country already hardened by death and destruction. <P3-S9>  The judge who oversaw the 1979 trial described their crimes as "a lasting monument to blind sectarian bigotry".
