[Harmonica intro]

Em        C     D         G
I want to live, I want to give
Em          C           D        G
I've been a miner for a heart of gold
Em           C         D       G
It's these expressions I never give
Em                           G        D
That keep me searching for a heart of gold
C                    G
And I'm getting old
Em                      G        D
Keep me searching for a heart of gold
C                  (riff)  G
And I'm getting old
