In 1967, Harry Reasoner narrated a TV doc titled “The Hippie Temptation.” At the center of that frightened little doc was a band called the Grateful Dead. Footage includes the Dead and friends interviewed at their now famous 710 Ashbury Street apartment, as well as performing a free concert in Golden Gate Park.
The Media Center at Moffitt Library, UC Berkeley Propaganda and Misinformation page describes the doc like this:
Hippie Temptation is a study of the lifestyle of hippies in San Francisco’s Haight-Ashbury district (narrated by Harry Reasoner looking like he’s about to explode!). Explores the reasons why young people become hippies and the great dependence of the hippie culture on drugs, especially their experimentation with LSD. Includes an interview and performance with a young, obscure rock group, the Grateful Dead.
Here’s a terrific snippet from that documentary:
