First off, this is a song by Nathan Caswell, a local guy. It's called Reflection on an Unusual Parcel Received in the Mail.

Pick up a parcel from the post, about two inches tall, by four inches wide
Cut the twine and tore the paper, you'll imagine my surprise at what I found inside

Chorus:
Singin' oh-oh bloody severed human ear in the mail
Make a fellow kinda pale
Singin' oh-ooh-oh better than a horse head in my bed
It's a human ear in the mail

Beneath the ear there was a note, I had to peel away the gore, so I could read it clearly
It said we've got your son under a gun and if you ever want him back, you're gonna have to pay us dearly
A million cash is the price on his life or his brains are gonna make quite a mess
I breathed a huge sigh when I remembered

I don't have a son
They must have got the wrong address
Chorus:

Beneath the note there was a Polaroid of a kid holding the note, sitting on a concrete floor
Bloody bandage on the side of his head, I never seen the kid before
So I wrapped it all back up again and tossed it in the trash
I didn't shed a single tear
They'll just have to try again, they better get it right this time
Kid's only got one more ear
Chorus
