They say a wish upon a shooting star

Will magic'ly be granted from afar;

Some demi-god that lives in Star-land there

Will send your heart's desire through the air.

But what kind of a demi-god would deign

To grant a wish wished on a shooting plane?

I'm having some trouble with the wording/rhythm, so any and all suggestions on this one would be most appreciated, as ever. Thanks, luvs!
