There's no guarantee that we'll see tomorrow 
 Heaven only knows how long we have 
 So there's no way I'll ever, for one second, let you wonder 
 Just how long my love for you will last 

 'Til my last breath, 'til I'm called on high 
 'Til the [bad word] and I see the light 
 To the very end, 'til I give in 
 To the last beat of my heart 
 No I can't swear that I'll be here for the rest of your life 
 But I swear I'll love you for the rest of mine 

 'Til my last breath, 'til I'm called on high 
 'Til the [bad word] and I see the light 
 To the very end, 'til I give in 
 To the last beat of my heart 
 No I can't swear that I'll be here for the rest of your life 
 But I swear I'll love you for the rest of mine 

 No I can't swear that I'll be here for the rest of your life 
 But I swear I'll love you for the rest of mine
