This sounds a lot like a variant on an old song from my boy scout days.

First you do a call and answer with the group repeating the leaders line

Oh you can't go to heaven
In the scoutmaster's car
Cause the doggone thing
Won't go that far

Then you repeat the verse in unison and then segue neatly into a chorus of:

I ain't gonna greet my lord no more
I ain't gonna greet my lord no more
I an't gonna greeeeet my loooord no more

with the extended vowels in the last line making up for the lack of a fourth line.
