But Yarrow sang quite a different tune on "The Early Show" Tuesday: the world premiere of his "Colonoscopy Song."
“People are uncomfortable talking about colonoscopies,” said Yarrow, 71, who wrote and recorded the song for CBS Cares after doctors discovered a potentially cancerous polyp during his own procedure.
Lyrics of "The Colonoscopy Song":Now the camera that they used is not like the ones on movie lots
When I had my colonoscopy, I had a question on my mind
Do we all look the same when the doctor sees us from behind?
Then I had the answer, I felt like such a fool
Cause the doctor smiled and said to me, "Your colon's really cool."
My colon's really cool, what a nice surprise
He sees a lot of colons, but my colon took the prize.
Then he added something that was even more divine
"We found a polyp hiding, Peter, but we caught it just in time
We found a polyp hiding, don't mean to sound so crass
But the polyp was discovered by a camera up ..."
My mother and my father spoke to me that very day
They said, "My son, it seems you've won the polyp prize, hooray, hooray, hooray!"
It's a camera that is tiny and it takes into your shots
It's a camera that is groovy; It can twist and turn and bend
To film your colon story and ensure a happy end.
So listen to me closely for this not a lie
Colon cancer can be beaten, if you are not camera shy
Call you doctor swiftly, no ifs or other buts
Schedule your colonoscopy, I know you've got the guts.
My colon's really cool, what a nice surprise
My doctor sees a lot of colons but mine took the prize
Mine took the prize, my friends, mine took the prize
My colon's really groovy, so my colon took first prize.
