What's the Use?
http://www.youtube.com/watch?v=wFFy-tkYDo0Easily one of the best songs on Cross Purposes, imo, but left off the domestic release. Sabbath management was never any good..
Seventh Star has the famous Hammersmith Odeon live show from 1986. The late Ray Gillen on vocals.
I think Forbidden will still be a weaker release, but with Loser Gets it All (one of the better songs on the album) and a proper mix, it will be a far more enjoyable listening experience. Sabotage is also my favorite.
