Spotify has 2 recorded versions of this song:

WHAT WILL WE DO WHEN WE HAVE NO MONEY? which appears to be a single recorded by Lankum in 2017. The arrangement is minimal: It begins with a single voice accompanied by a single drone note (which might be a harmonium) which doesn't begin to vary until the second verse. Some harmony voices join on the third verse. It has one additional verse:

What will we do if we marry a sailor?
All true lovers, what will we do then?
Only sail on his ships and we'll play on his lips
And we'll yodel it over again.

WHAT WILL WE DO IF WE HAVE NO MONEY? recorded by the Vox Hunters on their album "The Vox Hunters" (2017). This is a livelier cheerful version accompanied by an accordion.
