The album includes a cover of the Joan Baez song "Diamonds & Rust", a decision which was encouraged by producer Roger Glover in the interest of adding a track with commercial potential. Indeed, "Diamonds & Rust" was the first song by Judas Priest to receive radio play, and Baez herself reportedly enjoyed the cover. This was the band's second attempt to cover the track, and the earlier version from the Gull Records era was only released later on compilations and as a bonus track on reissues of "Rocka Rolla".
