Question: For which car bombing in Northern Ireland did Tim Hegarty and Ross Graham release a support album?

full_context: Document 1: Omagh bombing: The Omagh bombing was a car bombing that took place on 15 August 1998 in Omagh, County Tyrone, Northern Ireland. It was carried out by a group calling themselves the Real Irish Republican Army, a Provisional Irish Republican Army (IRA) splinter group who opposed the IRA's ceasefire and the Good Friday Agreement. The bombing killed 29 people (including a woman pregnant with twins) as well as injuring some 220 others, a death toll even higher than that of any single incident during what were considered 'the Troubles' (1968-10 April 1998). Telephoned warnings had been sent about 40 minutes beforehand, but were claimed to be inaccurate and police had inadvertently moved people towards the bomb.
Document 2: Damien Rice: Damien Rice (born 7 December 1973) is an Irish singer-songwriter, musician and record producer. Rice began his musical career as a member of the 1990s rock group Juniper, which were signed to Polygram Records in 1997. The band enjoyed moderate success with a couple of single releases, but a projected album floundered because of record company politics. After leaving the band he worked as a farmer in Tuscany and busked throughout Europe before returning to Ireland in 2001 and beginning a solo musical career, and the rest of the band went on to become Bell X1. In 2002 his debut album "O" reached No. 8 on the UK albums chart, won the Shortlist Music Prize and generated three top-30 singles in the UK. Rice released his second album "9" in 2006 and his songs have appeared in numerous films and television episodes. After eight years of various collaborations, Rice released his third studio album "My Favourite Faded Fantasy" on 31 October 2014. Rice's personal activities include musical contributions to charitable projects such as the , Freedom Campaign and the Enough Project.

Like the Provisional IRA before it, the RIRA sees itself as the only rightful successor to the original Irish Republican Army and styles itself as "the Real Irish Republican Army" in English or "Óglaigh na hÉireann" in Irish. It is an illegal organisation in the Republic of Ireland and designated as proscribed terrorist organisation in the United Kingdom and the United States.

Document 10: Lady's Bridge (album): Lady's Bridge is the fifth studio album from musician Richard Hawley, released on 20 August 2007 in the UK and on 9 October 2007 in the US. The album follows his 2005 Mercury Music Prize-nominated album "Coles Corner". It is named after the landmark location of Lady's Bridge in Hawley's hometown of Sheffield, an old bridge over the River Don that historically connected the rich and poor parts of the town. Hawley told "Uncut" magazine that "the title is a metaphor too; it's about leaving the past behind". The cover features a photograph, taken by Martin Parr, of Hawley and his guitar at the Club 60 music venue in Sheffield as a tribute to his father Dave who had died of lung cancer earlier that year: Dave Hawley had been a blues guitarist at the club in his youth, playing alongside Muddy Waters and John Lee Hooker.
Document 11: The Troubles in Magherafelt: A total of eleven people were killed in violence relating to the Northern Irish Troubles in the town of Magherafelt, County Londonderry. Nine were killed by the Irish Republican Army (IRA), including three IRA members killed by the premature explosion of their own bomb while travelling through Magherafelt. One was killed by a non-specific republican group and another by the opposing Ulster Freedom Fighters (UFF). Of the others killed by the IRA, four were Protestant civilians. Three of them were killed in two separate car bomb explosions. The fourth Protestant civilian was shot because his firm was a contractor for the British Army and the Royal Ulster Constabulary (RUC). The IRA's other two victims were both Protestant members of the security forces, one from the RUC and the other from the Ulster Defence Regiment. Both were off duty when killed. The man killed by the UFF was a Sinn Féin councillor who was shot in his workplace. The man killed by the non-specific republican group was a Catholic civilian.
Document 12: Now (The Dubliners album): Now is an album by The Dubliners released in 1975. Following the departure of both Ciarán Bourke and Ronnie Drew in 1974, singer/guitarist Jim McCann joined Barney McKenna, Luke Kelly and John Sheahan as a member of The Dubliners to record this album, which Sheahan himself produced. The slight shift in personnel produced a more mellow sound. Arguably, McCann's greatest contribution to the album is the ballad "Carrickfergus", which became one of his most popular and requested songs. It also features a wonderful rendition of the English ballad, "The Unquiet Grave", performed by Luke Kelly.
