Led Zeppelin

After a 23 July show[72] at the "Day on the Green" festival at the Oakland Coliseum in Oakland, California, John Bonham and members of the band's support staff (including manager Peter Grant and security coordinator John Bindon) were arrested after a member of promoter Bill Graham's staff was badly beaten during the performance. A member of the staff had allegedly slapped Grant's son when he was taking down a dressing room sign. This was seen by John Bonham, who came over and kicked the man. Then, when Grant heard about this, he went into the trailer, along with Bindon and assaulted the man while tour manager Richard Cole stood outside and guarded the trailer.[21][73] The following day's second Oakland concert[74] would prove to be the band's final live appearance in the United States. Two days later, as the band checked in at a French Quarter hotel for their 30 July performance at the Louisiana Superdome, news came that Plant's five year old son, Karac, had died from a stomach virus. The rest of the tour was immediately cancelled, prompting widespread speculation about the band's future.[12][26]
