Songs of freedom

Emancipate yourselves from mental slavery;
None but ourselves can free our minds..
Have no fear for atomic energy,
cause none of them can stop the time.
How long shall they kill our prophets, while we stand aside and look? ooh!
Some say its just a part of it:
Weve got to fulfil de book.

Wont you help to sing these songs of freedom?
cause all I ever have:
Redemption songs
