This was very interesting. When I was in grade school in the 1950's in rural Minnesota, we took the school bus. An older girl (she must have been in third grade when I was in second), Patty B., used to lead us in this song as a call and response also. I had never heard this song anywhere else. Including girl scout camp or church camp. I also thought the song was 'I ain't gonna GREET my Lord no more'. Grieve does makes more sense although at that time I figured since it was about not getting to heaven 'greet' did work all right. I especially remember the lines (which seemed quite risque at the time),

Oh you can't get to heaven (Oh you can't get to heaven)
In a strapless gown (In a strapless gown)
'Cause the Lord's afraid ('Cause the Lord's afraid)
It might fall down (It might fall down)

Then it was sung faster and louder without the response, with the last line being 'I ain't gonna greet my Lord no more.
