[C] Many,
many years ago when [G] I was twenty-three
I was married to a widow who was [C] pretty as could be
This widow had a
grown-up daughter [F] who had hair of red
My [D] father fell in love with her and [G7] soon the two were [G] wed
Chorus:
Now [G] I'm my own grand[C]pa, [F] I'm my own grand[D]pa[D*]
It may sound [C]funny I know, but [F]really
it's so
[C] I'm my [G] own grand[C]pa
D*: [x x 0 7 7 5]
this chord is optional!
This
[C] made my dad my son-in-law and [G] changed my very life
My daughter was my mother, 'cause she [C] was my father's wife
And
to complicate the matter even [F] though it brought me joy
I [D] soon became the father of a [G7] bouncing baby [G] boy
Now the
[C] little baby then became a [G] brother-in-law to Dad
And so became my uncle though it [C] made me very sad
Cause
if he was my uncle then this [F] also makes him brother
To the [D] widow's grown-up daughter who was [G7] also my step-[G]mother
Chorus
[C] Father's
wife then had a son who [G] kept him on the run
He became my grandchild 'cause he [C] was my daughter's son
My wife
is now my mother's mother [F] and it makes me blue
Be[D]cause although she is my wife she is [G7] my grandmother, [G]too
Now [C]
if my wife is my grandmother then [G] I am her grandchild
And every time I think about it [C] nearly drives me wild
For
now I have become the strangest [F] case you ever saw
As [D] husband of my grandmother, I [G7] am my own grand[G]pa
Chorus
Oh, [F] I'm my own grand[D]pa[D*]
It may sound [C]funny I know, but [F]really it's so
[C] I'm my [G]
own grand, [C] I'm my [G] own grand, [C] I'm my [G] own grand[C]pa
