Try Anne Lister - she's got a great song about them on a CD "Spreading Wings"

I have seen them on the wings of morning
On rosy clouds of dawn I've seen them fly
And I have seen them, their eyes dark with firelight
Their wings flashing sunlight across the sky
Don't talk to me of reality, don't talk to me of lies
If all you saw were clouds across the sky.

...and there are another four or so verses. (Anne had been reading Ursula Leguin, I believe.)
