I have all of Sonata's studio albums, but I've never heard of this song...
And speaking of Sonata, I have to give this shameless plug - in October 2006 (pre-shoulder tattoos), I played a show with an on-campus cover band I was in (for a class called Rock Combo, if you can believe it), and we covered "The Cage" - the big girl was our main singer, and she was actually good (though a total drama queen bitch), but she got the little girl to do guest vox, and yes, I know, she's horrible.
BUT - I'm very proud of my versions of the opening KEYBOARD solo (oy...) and the solo at 3:57, so those are the parts worth watching
