Lyrics:

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

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

Now 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 herself a lot of other man
But that ain't how folks used to love back then

Grandma was a motor...

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 it's kind of lovely here without his blue eyed girl
And he can't wait till heaven comes to call

Grandma was a motor...
Grandma was a motor but she let my grandpa drive
