For those who were interested, I did manage to find a few disgusting verses for "Early in the Morning". Same tune as the one Makem and the Clancy Bros. sing.

EARLY IN THE MORNING

Wake up. Mary. Get out of bed
Try if you are able.
Breakfast is ready, so shake out the lice.
We need your sheets for the table.

CHORUS: Early in the morning, early in the morning,
Early in the morning before the break of day.

Mary had a little lamb.
Her daddy shot it dead.
Now she goes to school with it
Between two slices of bread.

Jack be nimble. Jack be quick.
Jack jumped over a candle stick.
Silly boy, he should have jumped higher!
Goodness, gracious, balls of fire!

Georgie Porgy, pudding and pie,
Kissed the girls and made them cry.
When the boys came out to play
He kissed them too because he played both ways.

(I changed the last few words from the homophobic "because he was funny that way.")
