Commemoration events will take place to mark the 50th anniversary of the Miami Showband massacre.
On 31 July 1975, three band members were murdered by a loyalist paramilitary group at Buskhill in Co Down.
A commemoration event will take place at the site where surviving members and their road manager Brian Maguire will celebrate the lives of their band mates.
One of Ireland’s most popular entertainment and recording acts, the Miami Showband was targeted as they travelled home to Dublin following a gig.
A fake army patrol made up of Ulster Defence Regiment (UDR) soldiers and Ulster Volunteer Force members stopped them at the bogus checkpoint outside Newry, Co Down.
Band members were made to line up at the side of the road while attempts were made to hide a bomb on the tour bus.

The device exploded prematurely, killing some of the would-be bombers.
Their accomplices then opened fire on the band, murdering lead singer Fran O’Toole, guitarist Tony Geraghty and trumpeter Brian McCoy.
Two other band members, Des McAlea and Stephen Travers, were also injured but survived the atrocity.
In 2011, a report by the Historical Enquiries Team raised collusion concerns around the involvement of an RUC Special Branch agent.

It found that notorious UVF boss Robin ‘The Jackal’ Jackson, a one-time UDR member who died in 1998, had been linked to one of the murder weapons by fingerprints.
Jackson, a suspected RUC Special Branch agent linked to scores of murders, claimed in police interviews he had been tipped off by a senior police officer to lie low after the killings.
He went on trial charged with possession of a silencer attached to a pistol used in the murders but was subsequently acquitted.
Two serving members of the UDR were, however, eventually convicted for their part in the attack.
There will also be a number of other events taking place today in Newry, Dundalk and Dublin where there is a Miami Showband Monument at Parnell Square.
