As a result of the satellite broadcasts, U2 promised to play in Sarajevo. The Sarajevo show had to wait until the PopMart Tour, when U2 became the first major band to perform in the city after the war had ended. The highly emotional concert was among the highlights of the PopMart Tour. 45,000 people attended and effort was made to make sure all the ethnic groups were present. Also in attendance were several hundred members of the international "Stabilisation Force" (SFOR) who were tasked at that time with upholding the Dayton Agreement. During the encore, Brian Eno got on stage for the band's first ever live performance of "Miss Sarajevo." Luciano Pavarotti, who was guest vocalist on the original recording was not in Sarajevo.

Larry Mullen Jr. also played the leading drumbeat from the song as part of the second half of "Please". Despite the subpar performance, a news story said, "For two magical hours, the rock band U2 achieved what warriors, politicians and diplomats could not: They united Bosnia." Trains ran for the first time since the war to enable people to see the concert, though they were stopped again afterward. Bono later called the Sarajevo show "one of the toughest and one of the sweetest nights of my life." Mullen called it "an experience I will never forget for the rest of my life, and if I had to spend 20 years in the band just to play that show, and
