I guess this is the song you're looking for. The only person I know of to
record it was Ray Stevens, but there could be others. There's no tab just
lyrics and chords.

I¹m My Own Grandpa


No many many years ago when I was 23
I was married to a widow who was pretty as can be
This widow had a grown-up daughter who had hair of red
My father fell in love with her and soon they too were wed

Chorus:
O I'm my own granpa / I'm my own granpa
It sounds funny I know, but it really is so
O I'm my own granpa

This made my dad my son-in-law and changed my very life
My daughter was my mother cause she was my fathers wife
To complicate the matter even though it brought be joy
I soon became the father of a bouncing baby boy

chorus

My little baby then became a brother in law to Dad
And so became my uncle, though it made me very sad
For if he was my uncle, then that also made him brother
Of the woidows grown up daughter who was also my stepmother

chorus

Fathers wife then had a son who kept them on the run
And he became my grandchild, for he was my daughters son
My wife is now my mothers mother and it makes me blue
Because altho' she is my wife, shes my grandmother too

chorus

Now if my wife is my grandmother, then Im her grandchild
And every time I think of it, it nearly drives me wild
For now I have become the strangest case I ever saw
As husband of my grandmother, I am my own grandpa

chorus

The chords for the verse are

c-g7-/--c-/-c7f-/d7-g-/

and for the chorus
c cg c - / f fd g - / c c7 f d / c cg c - /

anyway, the song is a geniological nightmare...have fun
