(R)Evolution In Rock lyrics

We think it's right you call it left Vietnam to El Salvador, you just play deaf You don't want to hear a word we say Wanna make believe it's all okay Yes we know there's (r)evolution in rock You can see it everywhere Yes we know there's evolution in rock You can feel it in the air You don't care if you play rough You and your klan never get enough You don't care if you're wrong or right You'll just send the Marines in to fight Sick and tired of Uncle Sam The mad nuclear missile plans 'Cause your karma really smells You and your boys gonna rot in hell
