I will read this whole thread a bit later. But for right now, I scanned it and I did not see any mention of this song. (Sorry to be musical below the line. :-/ )
Here's the song from the modern Limeliters:


Regression Therapy

A while ago I felt so strange, I went to see a shrink.
He listened and he said your case is stranger than you think.
I feel a spirit from your past is trying to get through,
You'll need regression therapy to cure what's wrong with you!
And as he probed into my mind, I felt myself go back in time,
And friends I was amazed to find that what he said was true...

In 1474 I was born, Timothy Yancy,
A son of a peasant farmer, and the peasant farmer's fancy
I held a plow beneath each arm, and one more in between,
I caught the plague, and bought the farm in 1517.

In 1532 I was born, Frederick Blumer,
The son of a high-born gentleman, at least that was the rumor,
I lived a pure and Christian life, until my concubine
Came at me with a butcher knife in 1599.

In 1671 I was born, Abigail Neville,
The daughter of a Salem goodwife who was dealing with the Devil,
And at her trial the council frowned suspiciously at me,
But I proved innocent, and drowned, in 1693.

(cho.)
Singing: Hey, Ho, Oh Well, don't ask for whom tolls the bell,
Even if we go to hell, we're back tomorrow night.
I'm here, you're here, soon we're gone, but never fear,
We'll reappear upon this sphere, until we get it right.

In 1732, I was born, Reginald Baker,
I slipped through the doctor's fingers, and went straight back to my maker!
But I returned at five o'clock, an executioner's son.
And I was one chip off his block in 1761.

In 18 hundred and 9 I was born, Abraham Lincoln.
Well, I guess you know the rest of that one...

In nineteen recently, we were born of our mothers
And we've had a good time in this life, compared with all the others
Some day we'll all be back on cue, and if the fates allow,
We'll be each other's deja vu, 100 years from now.
