performance as part of the tour was on 28 August 1993 in Dublin, after which the song was retired and did not appear on any of U2's next three subsequent tours (PopMart, Elevation, and Vertigo). The song was revived a decade and a half later with the launch of the U2 360° Tour on 30 June 2009 in Barcelona, where it was once again performed as part of the encore. It was introduced by a robotic voice reading excerpts from the poem "Funeral Blues" by W. H. Auden, followed by Bono's appearance wearing a laser-studded jacket on a darkened stage illuminated only by a glowing steering wheel-shaped microphone that hangs from above. During the performance, Bono would alternatively embrace or hang from the microphone, or twirl around it, or swing it overhead to emphasize the lyrics. The New York Times said its use as "a love song that can double as devotional" helped keep the show's music and messages in balance, while the Chicago Tribune said that Bono sang the song with fervor as part of an encore during which "the show's outsized ambitions produced a neon-lighted moment that nearly justified the costly enterprise." Rolling Stone called the song's performance "one of the show's highpoints." "Ultraviolet" continued to be performed during the encore throughout the first two legs of the tour, with minor changes such as the use of a different introduction. The band also played the song during its television appearance on Saturday Night Live on 26 September 2009. In an appearance that avoided both their recent singles and best-known hits, "Ultraviolet" was played as the group's third number, in full 360° Tour staging style as the show's end credits ran by. The song has been performed on the Joshua Tree Tours 2017 and 2019, accompanied by images of historical female figures and achievers on the video screen. Covers The Killers reworked the song for the 2011 tribute album AHK-toong BAY-bi Covered. "Achtung Baby was U2's 'Holy shit!' moment," remarked drummer Ronnie Vannucci Jr. "I was in high school when it came out and we'd drive around in my friend's mom's car and rock that shit all the time. When we were asked to record a cover, 'Ultraviolet' was a unanimous choice. It's reassuring to know that we're still on the same page after all these years. We brought it back to its bare bones, dumbed it down a
