This song was on country play lists for a couple of weeks ten years or so ago, and disappeared suddenly without a trace--I don't know who wrote it, who performed it, and I don't know the second verse:

FORBIDDEN ANGEL

You kiss me like a woman, though you're only seventeen,
It's clear you're old enough to satisfy,
The world would call me guilty if I loved you all the way;
Oh, why does heaven let forbidden angels out to play?

Forbidden angel, I know I must let you go;
Though everything in me says love you, my better nature tells me no.
I love you so, I know I can wait to unlock heaven's door;
When my forbidden angel's not forbidden any more.

It's kind of a curious morality expressed by the song--the singer could, of course, marry the girl he claims he loves without running afoul of the law (unless the law requires parents' permission to marry before the age of consent). But his focus seems to be not on starting a life with his angel, but simply sleeping with her. But then morality these days gets curiouser and curiouser. --seed
