My recollection of this is slightly different, being as follows:-
There was a man who had two sons
And these two sons were brothers
Adolphus John was the name of one
And John Adolphus the other

Now these two men they bought a suit
They bought it on a Monday
Adolphus John wore it all the week
And John Adolphus on Sunday

Now these two men they had a horse
Oh dear it was so thin
They took it to the river side
And pushed the poor thing in

Now these two men they died they did
From eating fish and jelly
Adolphus John died on his back
And John Adolphus on his…..birthday

Now these two men are dead and gone
I'm sure you wish them well
Adolphus John went to heaven above
And John Adolphus…..as well
