A double album, "Speak of the Devil" represents the fulfillment of a contractual obligation, as Osbourne owed Jet Records two more records. Though the album has long been a fan favorite, Osbourne himself has publicly renounced "Speak of the Devil", stating that it was only released to satisfy a contractual obligation. The live versions of "Iron Man", "Children of the Grave" and "Paranoid" featuring Randy Rhoads which were originally intended to be part of "Speak of the Devil", were eventually released in 1987 on "Tribute", an album dedicated to the memory of the deceased guitarist.
