It's from "A Rare Conundrum" and goes like this (don't do the HTML thing, so hope it's not too confusing. I can photocopy the lyric insert from the LP if you want me to send it to you.

Out in the sun, playing at the ball,
In the world of a child with no cares at all,
My friend said, “Let’s play hide and seek.
Close your eyes and promise that you'll never peek.
Close your eyes. Count to a hundred.”

One to a hundred, I counted slow,
But I never did find where my friend did go.
Mom said she heard the other day,
“Your friend has gone so far away.”
Close your eyes. Count to a hundred.

Soon comes the morning with the rising sun.
Playing at the ball I'd just begun.
“Pat-a-cake, pat-a-cake, have no fear,”
Sang a voice I knew ringing in my ears.
“Close your eyes. Count to a hundred.”

“Why don't you come and play? Come play hide and seek
In the depths of the quarry woods. You’ll never find me there.
Come catch me if you can. Catch me if you can.

She will ask when I get home,
“What have you done today, my son?”
“I was playing ball on the corner street.
With my friend I was out playing hide and seek.”
Close your eyes. count to a hundred.
