From the song "Maggie May," from the album Every Picture Tells A Story. Written by Rod Stewart and Martin Quittenton
Nominated by Steven Wynn

I was only 15 years old when this song came out, but I always found it a little strange. After 37 years I realize what Maggie represents: the end of youth. Every generation has its Maggie May. She's the person who mocks you, no matter how young and cool you may think you are. "Middle age is coming, bro," she seems to say. And though with time we learn to live with it, we lament with Rod Stewart: "Maggie, I wish I'd never seen your face."

She was mortality, warning us, at 15, of the changes ahead.

That's my interpretation, anyway.
