Sunday is a television drama, produced by Sunday Productions for Channel 4 and screened on 25 January 2002.
 It dramatises the events of "Bloody Sunday" through the eyes of the families of the dead and injured, specifically those of Leo Young, older brother of John Young, who was killed on the day.
 The timescale covers events in the years prior to Bloody Sunday, and subsequent events up to and including the Widgery Tribunal.
Steve Wickham is an Irish musician.
 Originally from Marino, Dublin, but calling Sligo home, Wickham played violin on the classic U2 song "Sunday Bloody Sunday", as well as recordings by Elvis Costello, the Hothouse Flowers, Sinéad O'Connor, and World Party.

On Sunday July 11, 1943, the OUN-UPA death squads aided by the local Ukrainian peasants simultaneously attacked at least 99 Polish settlements within the Wołyń Voivodeship of the prewar Second Polish Republic under the German occupation.
 It was a well-orchestrated attack on people gathered for a Sunday mass at Catholic churches.The towns affected included Kisielin (Kisielin massacre), Poryck (Poryck Massacre), Chrynów (Chrynów massacre), Zabłoćce, Krymn, with dozens of other towns attacked at different dates with tens of churches and chapels burned to the ground.
 The Volhynian massacres spread over four prewar voivodeships including Wołyń with 60,000 victims, as well as Lwów, Stanisławów and Tarnopol in Lesser Poland with 70,000 Poles murdered for the total of 130,000 Polish victims of UPA terror.
 The Bloody Sunday of July 11, 1943, is not to be confused with the Stanisławów Ghetto Bloody Sunday massacre of 10,000 to 12,000 Polish Jews on October 12, 1941, before the Stanisławów Ghetto announcement.

War is the third studio album by Irish rock band U2.
 It was produced by Steve Lillywhite, and was released on 28 February 1983 on Island Records.
 The album has come to be regarded as U2's first overtly political album, in part because of songs like "Sunday Bloody Sunday" and "New Year's Day", as well as the title, which stems from the band's perception of the world at the time; Bono stated that "war seemed to be the motif for 1982."
Don Mullan (born 1956, Derry, Northern Ireland) is an Irish best-selling author/humanitarian and media producer.
 His book "Eyewitness Bloody Sunday" is officially recognised as a primary catalyst for a new Bloody Sunday Inquiry which became the longest-running and most expensive in British Legal History.
 Mullan, who is dyslexic, has spoken widely and was co-producer of a highly acclaimed and multi-award winning film about Bloody Sunday that was inspired by his book.
"Sunday Bloody Sunday" is a song by Irish rock band U2.
 It is the opening track from their 1983 album "War" and was released as the album's third single on 11 March 1983 in Germany and the Netherlands.
 "Sunday Bloody Sunday" is noted for its militaristic drumbeat, harsh guitar, and melodic harmonies.
 One of U2's most overtly political songs, its lyrics describe the horror felt by an observer of the Troubles in Northern Ireland, mainly focusing on the Bloody Sunday incident in Derry where British troops shot and killed unarmed civil rights protesters and bystanders.
 At the same time, the lyrics reject hate and revenge as a response, as noted in the line "There's many lost, but tell me who has won."
 Along with "New Year's Day," the song helped U2 reach a wider listening audience.
 It was generally well received by critics on the album's release.
The discography of Irish rock band U2 consists of thirteen studio albums, one live album, three compilation albums, sixty-seven singles, and eight extended plays (EPs).
 The band formed at Mount Temple Comprehensive School in 1976 as teenagers.
 In 1979, the group issued their first release, the EP "U2-3", which sold well in Ireland.
 The following year, the group signed to Island Records and released their debut album, "Boy".
 It reached number 52 in the UK and number 63 in the US.
 They followed it up with the release of "October" (1981) and "War" (1983).
 "War" was a commercial success, becoming the band's first number-one album in the UK while reaching number 12 in the US.
 The album yielded the singles "Sunday Bloody Sunday" and "New Year's Day" and have since become among the band's most popular songs.
 On the subsequent War Tour, the group recorded the live album "Under a Blood Red Sky" and concert film "", both of which sold well and helped establish them globally as a live act.
Laurence Joseph Mullen Jr. (born 31 October 1961) is an Irish musician and actor, best known as the drummer of the Irish rock band U2.
 Mullen's distinctive drumming style developed from his playing martial beats in a childhood marching band, the Artane Boys Band.
 Some of his most notable contributions to the U2 catalogue include "Sunday Bloody Sunday", "Pride (In the Name of Love)", "Where the Streets Have No Name", "Zoo Station," "Mysterious Ways", and "City of Blinding Lights".
The War Tour was a concert tour by the Irish rock band U2, which took place in 1982 and 1983 in support of the group's third album "War".
 The tour took place in Western Europe, the United States, and Japan, with new material from "War" taking an increasing role as the tour progressed.
 Venues were mostly halls, but some arenas were introduced later on.
 U2's performances were very well received both critically and commercially, especially in the United States where U2 broke through to become a major act.
 Scenes of lead singer Bono waving a white flag during the song "Sunday Bloody Sunday" became an emblematic image of this phase of U2's career.
 It was their first tour as full-time headlining act and their first to be profitable.
"Sunday Bloody Sunday" is a song by U2.
