TAKE HER OUT OF PITY
Bob Shane / Nick Reynolds / John Stewart

I had a sister Sally, she was younger than I am.
Had so many sweethearts, she had to deny them.
But as for sister Sarah, you know she hasn't many.
And if you knew her heart, she'd be grateful for any.

Chorus:
Come a lands man, a pins man, a tinker or a tailor;
doctor, a lawyer, soldier, or sailor.
A rich man, a poor man, a fool or a witty,
don't let her die an old maid but take her out of pity.

We had a sister Sally, she was ugly and misshapen.
By the time she was sixteen years old she was taken.
By the time she was eighteen, a son and a daughter.
Sarah's almost twenty-nine, never had an offer.

Chorus

She never would be scoldin'. She never would be jealous.
Her husband would have money to go to the alehouse.
He was there a-spendin'. She'd be home a-savin'
and I leave it up to you if she is not worth havin'.

Chorus
