Largest Festival Of Its Time

150,000 tickets went out for the Summer Jam of 1973. However, there were about 600,000 rock fans that were actually in attendance. This would mean that at least 1 from every 350 people who were living in the United States showed up to the show. On the other hand, the original Woodstock festival’s attendance was about 400,000, not to mention it went on for 3 days with several big musicians. We must remember though that there were no online streaming sites to listen to hit songs during the 70s.
