equipment was set up, plugged in and ready to be rolled on after a 10-minute act on a side stage. He was about to walk up the ramp to the stage when it was discovered that the hard disc of his synclavier, carrying all 25 minutes of synthesised music for his act, was missing. He said he could not play without it, turned round, walked down the ramp crying, with his band and other members of his entourage following him, and out of the stadium. There was an urgent need to fill the gap he had left and Tracy Chapman, who had already performed her act, agreed to appear again. The two appearances shot her to stardom, with two songs from her recently released first album: "Fast Car" and "Talkin' 'Bout a Revolution". Before the concert, she had sold about 250,000 albums. In the following two weeks, she was said to have sold two million. Wonder returned to the stadium, but turned down the request to use the same equipment as the present act on the main stage, Whitney Houston. Other members of the band said they would use other people's equipment. Finally, with time running out, Wonder agreed. Houston finished with three encores and the next act, Salt-N-Pepa, started on the side stage using three minutes and 30 seconds of pre-approved stage time. Following Salt-N-Pepa's performance, there was no announcement, no sound from the main stage until, out of the darkness, came the opening lines of "I Just Called to Say I Love You" and a huge roar from the audience. The lights came on and Wonder went into the rest of the set. With the loss of the programmed hard disc, he shouted the change of notes to the band.
