The cool part for me, is when I listen to the song, vocals aside, it SOUNDS like it could have been included on one of the early Dio albums. Maybe it's a case of reliving my youth to a certain extent. Again, I can't wait to hear the rest of it.
I think that some musicians mature to a point where they embrace their legacy w/o worrying about re-inventing the wheel or making a statement. That renewed sense of fun and the lack of self-consciousness often shines through the music and allow them to recapture the spirit.
Campbell, like Iommi, has battled w/ cancer - I don't know if it has anything to do with it, but both really play like they mean it.
