George Harrison went to the Haight with his then-wife Pattie Boyd, and walked around, eventually finding people recognized him and followed him around. He played guitar in the park. He wrote a large check to fund the Haight Ashbury Free Clinic.
IIRC he said he had expected some kind of alternate hippie-economy based on genuine values and having ownership of the neighborhood, and was disappointed that he didn't see any evidence of that. Just a bunch of idle people.
