Simon says

The list of songs that've managed the virtually impossible task of rhyming the words yacht, apricot and gavot is a very short one. In fact, there's only one.

The song is You're So Vain. And the songwriter is Carly Simon.

You'll be hearing a lot about both of them in the coming weeks, because Simon has a new memoir coming out. (Ironically, it's being published by Flatiron Books, and not Simon and Schuster, the publishing powerhouse Carly's father, Richard L. Simon, co-founded).

To be sure, Simon has led a colorful life that's included lovers from Mick Jagger to Warren Beatty. When she was married to James Taylor, they were at one point the richest entertainment power-couple with a heroin-addicted guitar-playing husband in all of Martha's Vineyard.

One thing Simon promises to address, sort of, in the book that has the entertainment press chomping at the bit (if you've seen Simon's smile you know why that last line is so funny) is one of the timeless mysteries of the music world: who exactly is You're So Vain about.

She's already said in past interviews one of the verses is about Warren Beatty. Beatty himself has said the whole song is about him. He's so vain. Which brings up a contradiction inherent in the song that's bothered me each and every time I've heard it.

The main lyric is "you're so vain, you probably think this song is about you...." Here's the thing: the song is about him. So is he so vain, or just right in what he's thinking? Discuss.

Admittedly it's not a mystery on the scale of say who shot JFK, or did we know about Pearl Harbor ahead of time. But I have to say I'm kind of curious. Maybe we'll find out, time will tell.

The one thing I know for sure is it's not about me.

As an only child, I have to say that hurts.
