The album's most commercially successful track, the single "You've Got Another Thing Comin, was a last-minute addition. According to guitarist K. K. Downing, "We were quite happy with the album, but decided late on that we could add one more song. I know we had some of the parts, but we set about completing "Another Thing Comin during the mixing sessions at Bee Jay studios. It came together quite quickly, and I seem to remember that we all had a good feeling about it, as it did sound like a good driving song and possibly a good radio track." Rob Halford expressed surprise at the song's success, saying "that track was buried. Normally the tracks you think are going to do stuff are at the front end of the release. But our friends at Sony said, 'We're going to go for this song.' And we didn't really know what was going on. But then the feedback was coming over: 'Hey, the record's buzzing in this town and that town', and it just took off."
