From Zappa and the Mothers’ classic 1968 skewering of the Beatles “Sgt. Pepper’s Lonely Hearts Club Band” and hippie culture, “We’re Only In It For the Money.” Proof positive that you don’t have to be a card-carrying Conservative to consider hippie culture insipid and annoying. Used during a pivotal scene in director Haskell Wexler’s terrific and notorious 1969 countercultural film “Medium Cool.”
