I think Dad's version is the Speaks one. I must get him to write down the full lyrics to another song he used to sing for us, which I've never found anywhere else (well, I did find a hint on Google Books once, but it seems to have gone now):

Brother Noah! Brother Noah!
Can I come aboard on the ark of the Lord,
'Cause it's raining awful hard and it's getting awful cold?
Brother Noah! Brother Noah!

No, you can't, sir! No, you can't, sir!
You can't come aboard on the ark of the Lord
'Cause you smoke cigarettes and you never pay your board,
No, you can't, sir! No, you can't, sir!
