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

Am             Bm                         G
Sing with me tonight, lets tear open the skies
                   F                       Am   F   C   G
And leave it all behind by singing this tonight
Am                 F               C             G    (Abm)
   I would never leave you for a chance, for a moment
Am                 F               C              G
   I would never leave you for a chance, in this lifetime
           (Abm)  Am                     F 
So leave it all behind... leave it all behind
                  C                      G    (Abm)
So leave it all behind... leave it all behind

C                 Am    F   C                 Am    F
