To help defray the tour's costs, the Jacksons sought a corporate sponsor. They had all but concluded a lucrative deal with Quaker Oats when King came to them with a deal he had already signed with Pepsi. Although it would pay them less money, they had to take it and break off talks with Quaker. Part of the deal was that Michael, who did not drink Pepsi, would have to do two commercials. He made sure that his face appeared minimally in them to avoid overexposing his image. During filming of one of the two commercials, Michael suffered second and third degree burns on his scalp when a firework effect malfunctioned, catching his hair on fire. Many people, including friends and associates of his, believe this incident is what sparked his problems with prescription drug abuse.
