  G5         D5  
Over the houses
A5                     E5
The streets and the trees
C5            G5            D5
Over the dogs down below
           B5         E5      
They'll bark at our shadows
     A5          C5           D5
As we float by on the breeze

D5               A5      
Tonight we fly
E5         C5          
Over the chimney tops
G5                D5
Skylights and slates ?
B5               E5
Looking into all your lives
A5                 C5
And wondering why
D5                           G5
Happiness is so hard to find

G5           D5        A5       E5
Over the doctor, over the soldier
C5           G5     D5     B5      
Over the farmer, over the poacher
E5          G5        C5        E5
Over the preacher, over the gambler
A5            C5        G5        D5
Over the teacher, over the rambler
A5         E5       C5        G5
Over the lawyer, over the dancer
D5           B5       E5           G5       C5         E5
Over the voyeur, over the builder and the destroyer,
A5         C5           D5        G5
Over the hills and far away

D5       A5
Tonight we fly
E5           C5
Over the mountains
G5                  D5
The beach and the sea
B5          E5         G5
Over the friends that we've known
       C5                E5
And those that we now know
A5           C5        D5       G5
And those who we've yet to meet

D5           A5
And when we die
E5   G5        C5
Oh, will we be
D5        B5
That disappointed
E5   
Or sad
G5                  C5
If heaven doesn't exist
E5                  A5
What will we have missed
 C5                             D5   
This life is the best we've ever had
