I remember the song, and I am looking for the lyrics as well
"Grandpa's getting younger everyday,
He even went and threw his cane away"

Someone said that Lulu Belle & Scotty used to sing it, but it
is not on any of their in print albums.

It was on the same album (78 rpm vinyl) with:
The Old Apple Tree or The Ole Apple Tree
"If my pappy had a know'd it
He'd be sorry that he grow'd it
For they hanged pappy up on that tree."
--Thaddeus
