Found a rare Black Sabbath song on Youtube after years of searching. Its a song called Scary Dreams and it was only ever performed live on the 2001 Ozzfest tour.
For years no one knew what i was talking about, but now Ive found it. I assume it may have been recorded during the abort 2001 album sessions, before Ozzy went off to finish his Down to Earth album.
I do hope that they actually release any completed tracks from these sessions with Rubin at some point. Would be nice
