Page "Led Zeppelin" Paragraph 33

After the 23 July show at the Days on the Green festival at the Oakland Coliseum in Oakland, California, Bonham and members of the band's support staff were arrested after a member of promoter Bill Graham's staff had been badly beaten during the band's performance.

The following day's second Oakland concert was 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, Plant received news that his 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.
