Led Zeppelin began their North American tour at Pacific Coliseum in Vancouver, Canada, before a sold-out audience of more than 17,000 fans. Around 3,000 additional people without tickets clashed with local police outside the venue.
Led Zeppelin performed before 6,000 people at Milwaukee Arena at a concert that had been moved from August 27. One reviewer wrote that the group started slowly but finished in great style, with the crowd gradually becoming captivated by the performance.
