This is high on my list in part for artist-atypicality, but I appreciate the song for its own damned sake.
Wow, that piano intro is almost exactly like the Elton John Border Song riff! At least it sounds like it to me.
O-M-G, I never noticed similarities of the intros.
In defense of my oversight, I rarely listen to Elton John and Black Sabbath back-to-back.
