D                A           G               D       
I don’t know the same things you don’t know
   D

D            A           G            D          D
I don’t know I just don’t know
D                A           G            D          D
And I forget the same things you forget
D            A           G                  D        
But you predict what surely hasn’t happened yet
  D


G
Ooh, ooh, ooh, ooh, ooh.
A
It’s a great big place
G
Ooh, ooh, ooh, ooh, ooh.
A
Full of nothing but space
G
Ooh, ooh, ooh, ooh, ooh.
A                                         D        D
And it’s my happy place
