Dm Am Dm

[Verse 1]
      Dm
I'm a young married man and I'm tired of life,
    C                        Am
Ten years I've been wed to a pale sickly wife,
      Dm                               C    Am
She's nothing to do only sit there and cry,
Dm          C          Am            Dm
Praying and praying to God she would die.

[Verse 2]
  Dm
A friend of my own came to see me one day,
   C                       Am
He told me my wife she was pining away,
   Dm                                    C         Am
He afterwards told me that she would get strong,
Dm         C           Am      Dm
If I get a bottle from dear Dr John.

[Chorus]
   Dm
Oh doctor, oh doctor, oh dear Dr. John,
     C                   Am
Your cod liver oil is so pure and so strong,
     Dm                                    C     Am
I'm afraid of my life, I'll go down in the soil,
      Dm              C             Am        Dm
If me wife don't stop drinking your cod liver oil.

[Verse 3]
  Dm
I bought her a bottle, well just for to try,
        C                           Am
And the way that she drank it you'd think she might die,
  Dm                                  C    Am
I bought her another, it vanished the same,
    Dm           C         Am         Dm
And then she got cod liver oil on the brain.

[Verse 4]
  Dm
I bought her another, she drank it no doubt,
    C                     Am
And then she began to get terrible stout,
    Dm                                        C       Am
And when she got stout well of course she got strong,
    Dm       C          Am      Dm
And I became jealous of dear Dr John.

[Chorus]
   Dm
Oh doctor, oh doctor, oh dear Dr. John,
     C                   Am
Your cod liver oil is so pure and so strong,
     Dm                                    C     Am
I'm afraid of my life, I'll go down in the soil,
      Dm              C             Am        Dm
If me wife don't stop drinking your cod liver oil.

[Verse 5]
   Dm
Me house it resembles a great doctor's shop
     C                       Am
It's covered in bottles from bottom to top
     Dm                                C     Am
Well early the morning the kettle does boil
          Dm           C          Am        Dm
You would swear it was singing of cod liver oil.

[Chorus]
   Dm
Oh doctor, oh doctor, oh dear Dr. John,
     C                   Am
Your cod liver oil is so pure and so strong,
     Dm                                    C     Am
I'm afraid of my life, I'll go down in the soil,
      Dm              C
If me wife don't stop drinking
   Dm
Oh doctor, oh doctor, oh dear Dr. John,
     C                   Am
Your cod liver oil is so pure and so strong,
     Dm                                    C     Am
I'm afraid of my life, I'll go down in the soil,
      Dm              C             Am        Dm
If me wife don't stop drinking your cod liver oil.
