A song about kidnapping (maybe)

Hello, this is the first ever post on this blog, and I'd just like to start off with a song about naive romance and psychotic devotion. I think the sadness of it has to do with the fact it was sang by kids. I don't know, still couldn't figure it out after all of these months..

"Tonight You Belong to Me" - Patience and Prudence
I know (I know)
You belong to somebody new,
But tonight you belong to me.

Although (although)
We're apart, you're part of my heart,
But tonight you belong to me.

Way down, by the stream
How sweet it would seem,
Once more just to dream in the moonlight,
My honey

I know (I know)
With the dawn that you will be gone,
And tonight you belong to me.

Just to little old me.

Hear for yourself (MP3)
