Verse:
Bb5   F5   C5  F5   G5

Darkness hides the faces  of we who hold the power. We don't need to be rich
We only need to be free

Bb5   F5   A5   G5

Chains of oppression
Never gonna break
But a day will come when we hold the key

Bb5   G5  Bb5  G5 C5

Time will remind us
That the people still have a choice
And we don't want violence
Until there's no other choice

Chorus:

G5  G5   Bb5   G5 C5 G5

But the river's gonna rise
Wash our struggles away
The sun is gonna shine
Shine down on a brand new day

Bells will be ringing
Flames reaching to the sky
Higher and higher
Fueled by the winds of change
Sweet taste of freedom
Fresh on the tips of our tongues
And the dust of the past is all that shall remain
Echoes of our voices
Ringing all through the town
Will drown out the memories
Of the days when we were bound

Chorus
