Revolution in their minds
The children start to march
Against the world in which they have to live in
And all the hate that's in their hearts
They're tired of being pushed around
And told just what to do
They'll fight the world until they've won
And love comes pouring through
Children of tomorrow live in the tears that fall today
Will the sunrise of tomorrow bring in peace in anyway
Must the world live in the shadow of atomic fear
Can they win the fight for peace or will they disappear?
So you children of the world, listen to what I say
If you want a better place to live in, spread the words today
Show the world that love is still alive you must be brave
Or you children of today are children of the grave
