I googled because the lyrics had been haunting me from childhood - remember it being sung by older brothers when I was 8-10 years old.
I remember:-

Morphine Bill and Morphine Bill
Were walking down 5th aveneue
Singing 'any avveth on me    )This is what the words sounded
Any avveth on you'            )like to a young boy.
They came to the riverside
Where they committed suicide
Singing 'any avveth on me
any avveth on you.'

Anyone know any of this or, hopefully, any MORE of this?
Best wishes
Ken
