This is an awesome song by an under-rated reggae band.  I attempted to figure out the 
because I can't find chords/tabs for this song anywhere on the internet but they may be a 
off so bear with me and if you have any suggestions I would be glad to make changes.

Intro:Dm


Dm
Jah Jah give us life to live
           F
So let us live
   Bb         Gm
So no feel no way
            F
When I man say

Dm
Jah Jah give us life to live
           F
So let us live
   Bb          Gm
So no feel no way
            F
When I man say

     Dm
The light struck the night
                 F
And the morning come
    Bb               Gm
So I've got to stay awake
                    F
To meet the rising sun

     Dm
The light struck the night
                 F
And the morning come
    Bb               Gm
So I've got to stay awake
                    F
To meet the rising sun


It just repeats that throughout the song.  The lyrics change a bit but the changes are 
the same places so that should give you an idea of how to play it.
