My dad sang:

Roll out that rubber tyred carriage,
Roll out that old tattered hack,
'Cause there's twelve men goin' to the graveyard
And eleven comin' back.

I always though that he credited Jack Teagarden as his source.

Manitoba Hal sings:

Put a gang of ukuleles on my hearse wagon
To raise hell as we roll along.

I like to follow this song with Didn't He Ramble.
I always imagine it taking place in New Orleans.
