Sometime after 2.30am on July 31 1975, five members of the Miami Showband were travelling back to Dublin on the road between Banbridge and Newry when they were stopped in the townland of Buskill by what they thought was a routine UDR (Ulster Defence Regiment) military checkpoint. What followed was the slaughter of three of the band members and the unintentional exposure of the involvement of British military personnel in directing and assisting unionist death squads in their murder campaign.
