This song is off of the Leaving Las Vegas soundtrack and it's really beautiful. 
These are all pretty close, but I don't know all the jazz ornamentation.



Ab       		 C7       
I'm gonna love you like nobody's loved you, 

     Fm7  
Come rain or come shine;

Bb7                      Eb7                Ab7            
High as a mountain and deep as a river, come rain or come shine.

   C#m7           Abm            C#m7 			Edim                    
I guess when you met me it was just one of those things;

	Fm      Cm                    C  B  D  A7  Ab7 G7 F#7
But  don't ever bet me, 'cause I'm gonna be true if  you let me.


 Ab       		 C7       

You're gonna love me like nobody's loved me,

      Fm7    
Come rain or come shine;

Bb7		  Gm7    B7         C7                
Happy together, unhappy together, and won't it be fine.

F7          			Bb7         
Days may be cloudy or sunny, we're in or we're out of the money,

  F7             D7      Gm7-5        C7      Fm7   Ab7   Bb7    Ebm
But I'm with you always, I'm with you rain or shine.
