In 1979, a New Year's Eve concert on the steps of the Sydney Opera House turned into a drunken bloodbath. Shortly after walking on stage (but not shown in this clip), Rolf Harris picked up one of the empty beer cans hurled at him and went to take a drink. "Ahh, it's empty!" Funny?

Soon, full cans of beer came flying out of the crowd. Harris got hit at least 3 times. Unfortunately, he sustained no injuries.

Later in the evening, however, Australia's legendary hard rockers The Angels were hit by cans, empty champagne bottles and sheets of signage, ripped from the front of the stage.

This was Australia's Altamont. Live concerts at the Sydney Opera House were banned for decades. Such levels of drunkenness and random violence were not unusual in Australia, then or since. Numerous people walked away with bleeding head wounds, 65 people were taken to hospital, and more than 40 were arrested.
