With the help of Gene, I transcribed it. So here it is for anyone else who might be interested.

FAMILY REUNION
(Jimmy Dickens)

Dear Kinfolks: It's a long, long time since I laid eyes on you.
I know I ain't seen Mary Lou since 1952.
So Mom and Pop have asked me if I'd write and let you know
We're planning on a big reunion in a week or so.

CHORUS: Gonna have a family reunion, family reunion,
And a good old fashion outdoor barbecue.
Gonna have a family reunion, family reunion,
And even if you're a 19th cousin, you're invited too.

Our old maid Aunt Virginia's comin'. So is Suzie Q.
And Dizzy Lizzy's gonna bring her brand new baby, too.
I guess old Uncle Joe will show up loaded to the gills.
But that's all right, 'cause I can guarantee hangover pills.

REPEAT CHORUS

Now Mary, you be sure to come. We'll have some fun again.
You know I've had a crush on you since I was only ten.
Remember when I kissed you, Mama said it was a sin?
But what's the harm in kissin' when you're kissin' kissin' kin?

REPEAT CHORUS
