Volunteers -- Jefferson Airplane

Look what's happening out in the streets Got a revolution Got to revolution
Hey I'm dancing down the streets Got a revolution Got to revolution
Ain't it amazing all the people I meet Got a revolution Got to revolution


One generation got old  One generation got sold
This generation got no destination to hold Pick up the cry
Hey now it's time for you and me Got a revolution Got to revolution
Come on now we're marching to the sea  Got a revolution Got to revolution
Who will take it from you  We will and who are we We are volunteers of America


this song is a call to take a stand against the US government and the war in Vietnam.

U.S. involvement escalated in the early 1960s, with troop levels tripling in 1961 and tripling again in 1962.  U.S. combat units were deployed beginning in 1965. Operations spanned international borders, with Laos and Cambodia heavily bombed. American involvement in the war peaked in 1968, at the time of the Tet Offensive. After this, U.S. ground forces were gradually withdrawn as part of a policy known as Vietnamization. Despite the Paris Peace Accords, signed by all parties in January 1973, fighting continued.                (wikipedia)
