Sunday Bloody Sunday

"Sunday Bloody Sunday" is a song by 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. 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 song has remained a staple of U2's live concerts. During its earliest performances, the song created controversy. Lead singer Bono reasserted the song's anti-sectarian-violence message to his audience for many years. Today, it is considered one of U2's signature songs, and is one of the band's most performed tracks. Critics rate it among the best political protest songs, and it has been covered by over a dozen artists. It was named the 272nd-greatest song by Rolling Stone on their list of "The 500 Greatest Songs of All Time".
