On the day of the AC/DC concert I was changing the brakes on an Audi 100. The hydraulic fluid dripped into my eye. I went to the hospital and had an eye-patch put on. I saw the show with one eye. For the Queen show I remember the spotlights. They were on cranes that hung from the sides of the stage and each of them had an operator that rode in a seat attached to the powerful bulbs. They could pull way back over the crowd or zoom in as a group for a tight closeup of Freddie Mercury.
