Best friend had just got home from Nam and I was 3 weeks away from joining the US Navy....they was a draft during this era. Concert was great. Tractor was better than I though for a leadoff band. We smuggled several big jugs of bali hi wine into the reserve seats. We eventually got caught and explained to the guy we intended to drink and not throw the glass jugs. He shrugged and said ok. One of the highlights of the concert was a bare chested lady wanting to dance on-stage. After being removed 3/4 guys held up a 4X8' sheet of plywood just in-front of the stage, on which she danced and shook her "bounty" :~)
