I was thinking of doing a poem from Alice in Wonderland, in Esperanto, followed by the English original. Not sure if this counts as a poem or song, but in Esperanto it rhymes at any rate. Actually it seems to rhyme more than the English version.

ESPERANTO:
"Ho, Limak', vi plirapidu!" la merlango plende ĝemas;
"Ĉar fokeno post ni sekvas, kaj la voston al mi premas!
Kelonioj kaj omaroj je fervoro ĉiuj bolas,
Kaj atendas vin sur sablo! Ĉu vi ankaŭ danci volas?
Vi konsentas, ĉu ne vere? Vi konsentas partopreni?
Vi konsentas. Ĉu ne vere? Ho, konsentu partopreni.
Ho, imagu vi la ravon esti supren altlevita!
Esti kun omar' kunulo for en maron forĵetita!"
"Ne! Tro longen!" diris la limak', skuante sin timeme,
"Mi ne volas." Al merlango do rifuzis li dankeme.
Ja konsenti li ne volis, li ne povis partopreni,
Ja konsenti li ne povis, li ne volis partopreni.
Fiŝamiko al li diris "Ne tre gravas la distancoj;
Aliborde estas ja alia lando kaj la Francoj!
Ju pli longen de Anglujo, pli apude al Francujo!
Do, ne timu! Ĉar sur ambaŭ bordoj jen por vi patrujo.
Vi konsentas, ĉu ne vere? Vi konsentas partopreni?
Vi konsentas, ĉu ne vere? Ho, konsentu partopreni!"
ENGLISH:
`"Will you walk a little faster?" said a whiting to a snail.
"There's a porpoise close behind us, and he's treading on my
tail.
See how eagerly the lobsters and the turtles all advance!
They are waiting on the shingle--will you come and join the
dance?
Will you, won't you, will you, won't you, will you join the
dance?
Will you, won't you, will you, won't you, won't you join the
dance?
"You can really have no notion how delightful it will be
When they take us up and throw us, with the lobsters, out to
sea!"
But the snail replied "Too far, too far!" and gave a look
askance--
Said he thanked the whiting kindly, but he would not join the
dance.
Would not, could not, would not, could not, would not join
the dance.
Would not, could not, would not, could not, could not join
the dance.
`"What matters it how far we go?" his scaly friend replied.
"There is another shore, you know, upon the other side.
The further off from England the nearer is to France--
Then turn not pale, beloved snail, but come and join the dance.
Will you, won't you, will you, won't you, will you join the
dance?
Will you, won't you, will you, won't you, won't you join the
dance?"'
