the infamous 'speak of the devil' (or 'talk of the devil' in the u.k.) live release from 1982. this album is full of stories. for example ozzy's vocal performance was so bad, that he had to redo them in studio during post-production. there is a myriad of more interesting tales around this, just check wikipedia. although i am not too much a fan of sabbath, i find these recordings quite entertaining for their historical value alone. scored this european first pressing on ebay. jet records. 1982
