"to be the antidote to Zoo TV". The idea had been inspired by the successful informality of the Elvis Presley 68 Comeback Special. Here, the band played quieter songs, such as acoustic arrangements of "Angel of Harlem", "When Love Comes to Town", "Stay (Faraway, So Close!)", and Lou Reed's "Satellite of Love". Many critics compared the B-stage performances to "busking" and singled them out as the shows' highlights. After leaving the B-stage, U2 often played "Bad" or "Sunday Bloody Sunday", with performances of "Bullet the Blue Sky" and "Running to Stand Still" following. For "Bullet the Blue Sky", the video screens displayed burning crosses and swastikas. During "Running to Stand Still", Bono mimed the actions of a heroin addict from the B-stage, rolling up his sleeves and then pretending to spike his arm during the final lyric. Afterwards, red and yellow smoke flares ignited from either end of the B-stage, before the band re-grouped on the main stage to play older songs with more sincerity. "Where the Streets Have No Name" was accompanied by sped-up video of the group in the desert from The Joshua Trees photo shoot. U2 often finished their set with "Pride (In the Name of Love)" while a clip from Martin Luther King Jr.'s famed 3 April 1968 "I've Been to the Mountaintop" speech was played on the video screens. The group was initially unconvinced that the leap from the rest of the show's irony and artifice to something more sincere would be successful, but they thought that it was important to demonstrate that certain ideals were so strong and true that they could be held onto no matter the circumstance. The group alternated between performing "I Still Haven't Found What I'm Looking For" acoustically on the B-stage and using it to conclude the main set. Encore Beginning with the "Outside Broadcast" leg, footage from the tour's "video confessional booth" was displayed on the video screens during the intermission. Before each concert, fans were encouraged to visit the booth—a converted chemical toilet near the mix station—and record a 20-second confession. The video crew would then edit together the confessional footage to broadcast later that evening before the encore. The "confessions" varied from a woman flashing her breasts to a man revealing he had injured people in a drunk-driving accident. The inspiration for the video confessional came the day before the "Outside Broadcast" leg officially began. For
