Simplified version of the song on the ukulele. 
    
     C                 Dm        
Who knows how long I've loved you?
     C               Em
You know I love you still
        F              Am      
Will I wait a lonely lifetime?
        F      G      C     
If you want me to, I will


C         Dm        
If I ever saw you
    C                Em
I didn't catch your name
         F             Am       
But it never really matters
         F              C     C7
I will always feel the same

[CHORUS]
   F                Am    
I love you forever and forever
F                     C     
Love you with all my heart
F                  Am
Love you whenever we're together
D7                    G
Love you when we're apart


C               Dm       
When at last I find you
       B               Em
Your song will fill the air
         F             Am      
Sing it loud so I can hear you
          F          Am      
Make it easy to be near you
         F        G     Am        C7
All the things you do endear you to me
F        G      C
Oh you know I will

[chorus]

C               Dm        
When at last I find you
       B               Em
Your song will fill the air
         F             Am      
Sing it loud so I can hear you
         F          Am      
Make it easy to be near you
         F        G     Am        C7
All the things you do endear you to me
F        G     G#
Oh you know I will
   C
I will
