What Happened in the Year 1975?

In 1975, I graduated from high school. The Wheel of Fortune played on the television for the first time. Damage of $30,000 was caused by 1,000 Led Zeppelin fans, due to a riot while waiting at the ticket booth at Boston Gardens to get tickets for the concert. The Eagles rock band was very popular, and had a song that hit #1 on the billboard charts.
