Standard Tuning
I play this on my acoustic and it sounds good.
(G#m is optional, I don't play it)

A5             B5                         G5
Sing with me tonight, lets tear open the skies
                   F5                       A5   F5   C5   G5
And leave it all behind by singing this tonight
A5                 F5               C5             G5    ( Ab5 )
   I would never leave you for a chance, for a moment
A5                 F5               C5              G5
   I would never leave you for a chance, in this lifetime
           ( Ab5 )  A5                     F5 
So leave it all behind... leave it all behind
                  C5                      G5    ( Ab5 )
So leave it all behind... leave it all behind
