Two minutes and fifty seconds into the song, a long message in Morse code plays in the background.[3] John Woloschuk, in an article in the fan magazine The Morning Sun, finally provided a translation of the code:
"From Alfred, heed thy sharpened ear โ A message we do bring โ Starship appears upon our sphere โ Through London's sky come spring."[4]
The harpsichord sound on the song was created by recording a tack piano with the tape recorder running at half-normal speed.[5]
