Grandma was the only woman grandpa ever loved
At least that's what my Grandpa told my dad
And how I used to like to sit and watch him reminisce
On all the times that he and grandma had

Grandma was the motor and the mainspring of his life
Forty some odd years she was his wife
Now an old man and his memories keep a love affair alive
Grandma was the motor but she let my grandpa drive

Grandpa said that grandma had the kindest kind of soul
And her beauty didn't die when she got old
And he said she could have had herself a lot of other men
But that ain't how folks used to love back then

Grandma was the motor and the mainspring of his life...

Now grandpa he ain't got a lot of time left in this world
But he don't seem to mind it much at all
Cause he says he's kind of lonely here without his blue-eyed gir
And he can't wait till heaven comes to call

Grandma was the motor and the mainspring of his life...

Now an old man and his memories keep a love affair alive
Grandma was the motor but she let my Grandpa drive
