Charlemagne the Musical?

I heard it from RevolutionSF first, but apparently Christopher Lee is going to be playing the Ghost of Charlemagne in a concept album for a "symphonic metal" musical called "Charlemagne: By the Sword and the Cross." It seems that Christopher Lee is related to Charlemagne, although I don't know if that's why he's doing this CD. You can hear samples from the CD, which is set to come out on March 15 (although it isn't listed on Amazon), on its youtube page. Frankly, the music sounds pretty Transiberian Orchestra-ish to me, but that's probably because I have a limited reference pool when it comes to metal, even symphonic metal.
