"Shoe my Donkey, Shoe my Donkey, Shoe my Donkey's big toe" (bis)

and for the second measure,

"Oh, we shoe'd him in France,
And we shoe'd him in Spain,
Then we came back to Ireland, and
Shoe'd him again!"

(the word "my" tends to be pronounced "mi" - rather shorter than "me" - and "donkey" is pronounced "Dunky", to rhyme with "monkey")
