This song comes from Wild in the Streets
, which may be the most "'60s" movie ever made. It stars Christopher Jones, Hal Holbrook, and Shelley Winters.
Released on May 29, 1968, the film is about an acid-dealing hippie named Max Flatow (Christopher Jones) who blows up his father's car with dynamite, changes his name to Max Frost to become the world's biggest rock star, then uses his fame to break into politics and lower the voting age to 14.
The film is intentionally absurd, but it touched upon real concerns of the era. The Baby Boomer generation was starting outnumber their elders, meaning young people were having an outsized influence on the country in a way no one was used to dealing with.
LSD was a concern, as well, and it plays a major role in the film as Frost and his hippie army spike the Washington DC water supply with it and "turn on" the entirety of Congress.
Frost's character, while somewhat cartoonish, stems from an abusive household with a domineering, materialistic mother and a boyish father who fight endlessly. Though Frost becomes King of the Hippies, he's not portrayed as a loving sort. Instead, he's an angry, resentful young man, the result of an emotionally abusive upbringing. This shows a more nuanced view of the era's revolutionary counterculture personalities.
