“Stop hey what’s that sound, everybody look what’s going’ down”
“For What It’s Worth” by Buffalo Springfield.
Everyone thinks that was an antiwar anthem but the song actually was inspired by “the Sunset Strip curfew riot” of 1966.
Hollywood businesses were fed up with SoCal teenagers (I was one) loitering and creating a nuisance and driving away business. So they imposed a 10pm curfew with the predictable result of teenagers and idiot Hollywood celebrities protesting and getting arrested.
