Yes, I suspect lots of us were probably misled at School into assuming that poetry was just about sticking rhyming words at the end of every line (rather than sometimes internally within the lines), and also only going for rhymes involving the vowel sounds (plus the ending consonants). Hence we get cliches like moon and June, but so little attention would be drawn to the likes of moon and moan, moon and cool, moon and mist, etc, even though they served scribblers like Will Shakespeare very well.

As for identical rhymes, where would pop song lyricists, from Buddy Holly onwards, be without such ’ear worm’ repetitions? “I love to love, but my baby just loves to dance…”
