This isn’t Mormon poetry, but it was published in the Juvenile Instructor in 1902, taken from some unrecorded publication (it’s marked as “selected” poetry; Googling shows some sources giving credit to the Washington Star). My Facebook friends enjoyed it so much that I’d better post it here for everybody. You can sing it to the tune of “If You’re Happy and You Know It” – if you come up with another tune that fits, please suggest it.
Oh, let us all be joyous while we may,
Though the scientists annoy us every day.
For they agitate the topic
Of these creatures microscopic,
’Till we’re getting misanthropic, old and gray.
So now to drown our sorrow let us try,
Lest some microbe on the morrow should draw nigh,
Let the song and dancing thrill us,
Let’s forget that a bacillus
Hopes with all his heart to kill us by and by.
