The correct Wolfe Tones lyrics are:

Feed the pigs and milk the cow, milk the cow, milk the cow.
Feed the pigs and milk the cow so early in the morning.
Cock your leg up, Paddy dear, Paddy dear; I'm over here.
Cock your leg up, Paddy dear; it's time to stop your yawnin'. Chorus

Katie she is tall & thin, tall & thin, tall & thin.
Katie she is tall and thin, likes her drops of brandy.
Drinks them in her bed at night. Drinks them in her bed at night.
Drinks them in her bed at night. Makes her nice and randy. Chorus

My man is 6 ft. tall, 6 ft. tall, 6 ft. tall.
My man is 6 ft. tall. He likes his sugar candy.
Goes to bed at 6 o'clock. Goes to bed at 6 o'clock.
Goes to bed at 6 o'clock. He's lazy, but a dandy. Chorus

The wife she has a hairy thing, a hairy thing, a hairy thing.
The wife she has a hairy thing. She showed it to me on Sunday.
She bought it in the furrier shop, bought it in the furrier shop,
Bought it in the furrier shop. It's goin' back on Monday. Chorus.
