- Orphaned Reference: The Black Smoke is only ever mentioned as not working against the Thunder Child. It is also briefly mentioned during the scene at the Parson's house. The part where its nature and threat is explained was cut for time.
- What Could Have Been: Jeff Wayne originally wanted John Lodge to sing lead vocals on "Thunder Child", in an homage to Lodge's Vocal Tag Team with Justin Hayward in The Moody Blues (especially as Hayward sang the previous song on the album, "Forever Autumn"). Lodge recorded a take of the song but Wayne felt his vocal timbre wasn't strong enough for its key, so Wayne eventually took Chris Thompson from Manfred Mann's Earth Band instead.
