"Dead On Time" is of "Jazz" the seventh studio album by British rock band Queen, released on 10 November 1978. "Dead on Time", written by May, features some of the fastest and most aggressive guitar work by its author, as well as intense drumming by Taylor. The song contains two high belts by lead singer Freddie Mercury that top at C#5. Performed at high tempo for Queen, it was considered by most fans to be an ideal live number, but was curiously never played in concert; May would only incorporate snippets of it in his guitar solos during the Jazz Tour. The song resembles "Keep Yourself Alive" from Queen's self-titled debut album. In the last chorus, the words "keep yourself alive" are sung, and in the lyrics attached to the album, those words are written in capitals. The song ends with the sound of a thunderbolt, followed by Mercury screaming "You're dead!" The thunderbolt was actually recorded by May on a portable recorder during a vicious thunderstorm. The album's liner notes credit the thunderbolt to God.
