Am
I'm a young married man and I'm tired of life
G
For years I've been married to a poor sickly wife
Am                                            G
She does nothin' all day but to sit there and sigh
Am              Em              Am 
Wishin' and prayin' that she-ee could die

[Verse 2]
Am
A friend from the village was talkin' one day
G
I told him me wife was a-fadin' away
Am                                       G
He afterwards told me that she would get strong
Am         Em          Am
If I got a bottle from old Doctor John

[Verse 3]
Am          
Well I bought her one bottle to give her good cheer
G
The way that she drank it you'd swear it was beer
Am                                  G
I got her a second, and it went the same
Am                Em        Am  
I think she's got cod liver oil on the brain

[Verse 4]
Am
Oh doctor, oh doctor, oh dear doctor John
G
Your cod liver oil is so pure and so strong
Am                                        G
I'm afraid of me life I'll go down in the soil
Am                    Em            Am
If me wife don't stop drinkin' your cod liver oil

[Verse 5]
Am
Well it gave her good cheer and of that there's no doubt
G
Each week she got better and then she got stout
Am                                      G
And as she got fatter of course she got strong
Am                Em       Am
I think there's a devil in old Doctor John

[Verse 6]
Am
There's bottles and bottles all over the house
G
But as she got strong I'm as quiet as a mouse
Am                                         G
I've got to the stage if the kettle should boil
Am               Em         Em
I'd swear it was singing of cod liver oil
