I found an mp3 file at the web site of The Buffalo Sabres Alumni Association. The sound quality is poor; hence a few gaps and uncertainties. The performer is Jim Schoenfeld.

BARBECUE IN HEAVEN
John Valby

CHORUS: There'll be a barbecue in heaven when I get there.
I'm getting hungry just waiting to go.
There'll be a barbecue in heaven when I get there.
I hope I get to go.

Life's long; work's hard; kids to raise and feed;
And every day I gladly pray for the Judgment Day.
There'll be a crowd in the sky, the angels say.
"Howdy, son! Come on in. Stick it on your grave(?)."

When I was a little boy, my daddy said, "Now, son,
Bury me with a ... when you put me in the ground.
When I pass through the Pearly Gates and smell that pit-fire burning,
Jesus cookin' barbecue ... down."
