To ask if anyone knows this song?

[SupermassiveBlackHo]

This is a very long shot!
We used to sing a song in school about 30 years ago. It was a religious based song and was to do with the census being taken, and the spelling of people's names.

I can remember a fairly large chunk, which went:

"Habbakuk, 2 Ks or 3? Ezra, Z or S? How on earth d'you spell Jehoshaphat?
I've got news for you, my friend. As far as I'm concerned...
Your name's Smith! And that my friend is that."

Does anyone remember this song?? I've Googled and can't find a thing!

And if anyone's feeling super into finding old songs and poetry, there's a poem I'd love to remember too.

All I have to go on with is that it started,

"Would you give me a clue as to what I should do..."
