It's a general rule for introductory words rooted in the English language that serves as the first rung. Eventually it sinks in that there are other words that don't follow the song– most other words; but it's just a song. You don't take away a childhood, educational song about colors because it doesn't cover all of the colors either. This is impudent and uncool. As a mostly british gentleman, I want you to know that I don't support this in the least bit. It's not like I go to spell a word that I know doesn't follow the rule, and then think to myself– "Yeah...but the song said that it was–".

This is just plain silly. There's a reason this story is being posted in the 'Oddly Enough' sections of the world, and it's because you have to ask "What do they care?" Ban a miniature children's rhyme.
