in Chicago indicate "Bad" is about a friend of his who died of a heroin overdose and also about the conditions that make such events likely to be repeated. Bono once commented in another concert (in the UK) about people lying in gutters with "needles hangin' outta their fuckin' arms while the rich live indifferently to the suffering of the less fortunate." At Eriksberg, Gothenburg in Sweden 1987, he said: "I wrote the words about a friend of mine; his name was Gareth Spaulding, and on his 21st birthday he and his friends decided to give themselves a present of enough heroin into his veins to kill him. This song is called 'Bad.'" During a 26 July 2011 concert in Pittsburgh, Bono introduced a performance of "Bad" as a song written for a "very special man, who is here in your city, who grew up on Cedarwood Road. We wrote this song about him and we play it for him tonight." He was referring to Andy Rowen, whom the song was written about in 1984 and who was present at the show. Rowen is the brother of Bono's Lypton Village friend Guggi and Peter Rowen, who is featured on the sleeve artwork for the band's albums Boy and War. Live performances "Bad" is one of the band's most performed songs. Translating the elaborate and complex textures of the new studio-recorded tracks to live performance proved to be a serious challenge when The Unforgettable Fire Tour commenced. One solution was programmed sequencers, which the band had previously been reluctant to use. Sequencers were prominently used on "Bad". The studio version of "Bad" was criticised as being "unfinished", "fuzzy" and "unfocused", but the band found that it made more sense on stage. Rolling Stone, for example, critical of the album version, described its live performance as a "show stopper". A staple of U2's concert tours of the 1980s, "Bad" was also frequently performed during the first four legs of the 1992–1993 Zoo TV Tour. Although not played until the fourth leg of the PopMart Tour of 1997 and 1998, it returned to the normal set list for 2001's Elevation Tour and saw occasional performances during the Vertigo Tour of 2005 and 2006, sometimes even appearing as the closing song for shows. It made very sporadic appearances on the U2 360° Tour and has featured occasionally on the Innocence + Experience Tour. The
