The 24-second, black and white clip was unearthed by local news station CBS News 8, and shows the Beach Boys and entourage feeding the goats who eventually adorned the album cover.
The origins of the shoot remain shrouded in mystery. Beach Boy Al Jardine has claimed that Capitol Records hadn’t actually listened to Pet Sounds and assumed it was about animals, while a contemporaneous report in the San Diego Union states that the choice of location was a reference to UK band The Animals.
Either way, the shoot did not going entirely according to plan, with the Union's Frank Rhoades snootily describing the band as, "six millionaire-musicians... with long Beatle hair and all wearing funny boots."
"One of them bounced a carrot off the head of one of our tigers," wrote Rhoades. "Another tried to stick the head of a little antelope through some iron bars. Then they went around handling puppies and baby chicks, putting them down in the open and walking off.
“A few young girls who saw the Beach Boys acting like this were certainly disillusioned. The cameraman and the art director were awfully nice guys, but things just got out of hand and they couldn’t control the situation.”
Rhoades finished by claiming that the zoo's superintendent, an ex-Marine sergeant major named John Muth, had told the band they were not welcome back and never would be.
Beach Boy Mike Love remembers things differently, telling CBS News 8, "Hey now, wait a minute, let's let bygones be bygones. I have no idea why they said that. Maybe something rude was said or done but I comported myself as a perfect gentleman."
But fellow Beach Boy Brian Johnston has been less conciliatory in the past, accusing the goats themselves of behaving badly.
“The goats were horrible,” Johnston told Rolling Stone, several decades after the event. “They (would) jump all over you and bite. One of them ate my radio. The zoo said we were torturing the animals, but they should have seen what we had to go through. We were doing all the suffering."
None of the goats were available for comment.
