 According to historian Jon Wiener, "Revolution" inspired the first "serious debate" about the connection between politics and 1960s rock music.The counterculture's reaction was especially informed by news footage of the violent scenes outside the Democratic National Convention on 28 August, and of Soviet tanks invading Czechoslovakia, which marked the return of communist oppression there and the end of the Prague Spring.The song prompted immediate responses from the New Left and counterculture press, most of whom expressed disappointment in the Beatles.
