The Vowel Song

I made up a song, The Vowel Song, sung to a tune from Final Fantasy X - the Song of Prayer. Here is an example:

Song of Prayer - Ifrit

I made up the song while I was playing the game a few months ago while Kyra watched. I wasn't sure what the words were, so I made up the tune so I could still sing it. Here are the lyrics, and it only lasts the first few phrases of the Song of Prayer:

A E I O--
U - - - -
I know my vowels
How 'bout you----?

It hasn't yet become useful in teaching vowels to Luca, but one day it might.
