The Old Man's Lament - Buffy Sainte-Marie

On a bright summer’s evening I chanced to go roving

Down by the clear river I rollicked along

I heard an old man making sad lamentation;

He was rocking the cradle and the child not his own

Cho: Hi ho, hi ho, my laddie lie aisy

For perhaps your own daddy might never be known

I’m sitting and sighing and rocking the cradle

And nursin' the baby that’s none of my own

When first that I married your inconstant mother

I thought myself lucky to be blessed with a wife

But for my misfortune, sure I was mistaken

She’s proved both a curse and a plague on my life

She goes out every night to a ball or a party

And leaves me here rockin' he cradle alone

The innocent laddie he calls me his daddy

But little he knows that he’s none of my own

Now come all ye young men that’s inclined to get married

Take my advice and let the women alone

For by the Lord Harry, if ever you marry

They’ll leave you with a baby that’s none of your own

(or «and swear it’s your own».)
