Oh, speaking of metal versions of Rocky songs I have to share this one:
http://www.rockymusic.org/mp3/castalbum ... dic-07.mp3
That's "Hoppum Út Um Allan Sal (Hot Patootie)" from the 1995 Icelandic cast album of The Rocky Horror Show. For whatever reason, they completely reimagined the song as an ode to Death Metal. The whole thing is in Icelandic, except that they say "death metal" in English for the chorus. So instead of "Hot Patootie Bless My Soul..." it goes "Hoppum út um allan sal. Ó, ég dái death metal". It's a trip.
it means, "Hop all around the room, I admire death metal".
