LOVE, LOVE, LOVE this song and the lyrics and the music and the way Don sings it, etc.... There's a reason this song is a favorite of so many people who don't even claim to be Eagles fans.
I agree that it's a song about a man in search of that perfect woman (good luck--they don't exist!) and in MY mind, he's actually looking for one who leans more to the daughter of the devil himself. With lines like,
The full moon is calling
The fever is high
And the wicked wind whispers and moans
You've got your demons
And you've got desires
But I got a few of my own
I'm thinking he looking for one that leans towards the "naughty".
Or it could just be my dirty mind and the way he sings it. And I've thought that way for over 30 years about this song so no one burst my bubble now.
