I'd guess that Happy Land has as many or more parodies than Beulah Land (such as "Dakota Land").

When I was a kid my father used to sing one very similar to the boarding house/Happy Land variation mentioned above:

There is a boarding house, far, far away
Where they serve ham and eggs, three times a day
Oh how the boarders yell
When they hear the dinner bell
Oh, how those eggs do smell,
Far, far, away.

I vaguely remember that he might have gotten that from Burl Ives? It was one of his earliest songs and he was still getting a lot of them off of records. It falls in the same type of down-and-out and hobo songs as "Big Rock Candy Mountain" that Ives was singing. Note to self to go check the 10" LP I think it might have come from.

Barre Toelken is an anthropologist and folklorist who made a study of how Beulah Land went through transformations over time - I suspect the same arguments could be made for Happy Land. I heard Toelken talk about it in a concert he gave - what he discussed was probably a fraction of the material he had, and it might be worthwhile checking to see if he looked at other popular hymn tunes and lyrics as well.
