F5         C5      
Whenever I look back
G5                          A5 (quick)
On the best days of my life
F5        C5              G5   A5 
I think I saw them all on T.V.
F5      C5      
I am so homesick now for
G5                         A5
Someone that I never knew
F5      C5 
I am so homesick now for
G5
Someplace I will never be

F5   C5           G5    A5        
Time won't let me go
F5   C5           G5    A5   
Time won't let me go
F5           C5
If I could do it all again
G5                                A5
I'd go back and change everything
F5       C5             G5    A5
But time won't let me go


Same throughout song until bridge:

Dm5
If I could go back once again
C5                       G5
I would change everything, yeah
Dm5                      C5
If I could go back once again
                       G5
I'd do it all so much better


F5, C5. G5, A5, etc.
