The gig was scheduled for Sunday afternoon, July 3. The day before, performances by Ray Charles and singing group Lambert, Hendricks and Ross were met with unruly crowds. About 300 drunken revelers made a commotion during Charles' performance and the police responded with teargas and water hoses. The riots became so out of control that the National Guard was called in at midnight to calm the crowd. When Waters and his band arrived on the scheduled day, they intended to drive back on the next day, until driver James Cotton saw John Lee Hooker standing at a corner, his guitar on his back without a guitar case. Cotton said Hooker should get into his car to get the musicians out of harm's way. At the same time, the city council decided to cancel the concert, but concert promoter George Wein convinced them when he said that the United States Information Agency (USIA) planned to film the festival to teach American culture in other countries
