When listening to the song, it is very easy to confuse the singers with John Lennon and Paul McCartney due to an uncanny resemblance to their voices. This combined with the extremely Beatlesque sound of the instrumentals can make this song sound similar to something the Beatles might do, namely because the chord progression of this song were similar to the Beatles' "Blackbird" and "It's All Too Much", as an homage to the band.
This song (as well as the less Beatlesque "Calling Occupants of Interplanetary Craft") were the base of the "Klaatu are Beatles" rumor.
It seems there were some interesting little bits put into the song. For instance, at two minutes and fifty seconds into the song, a long message in Morse Code plays in the background. 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 -- A message we do bring -- Starship appears upon our sphere -- Through London's sky come spring."
Also, when played in reverse, some claim one can hear messages such as whispered "Listen, listen, listen" and "I don't know, I don't know, it's Alfie".
