También las Canciones de Klaatu tienen Mensajes, incluso hay Mensajes en Clave Morse:
At this point there is some Morse Code in the recording which several interviews over the years have not been able to uncover the meaning of. I have also heard of people who have tried to decipher it themselves without any luck.

Well, you are in luck! Steve Radley has pointed out that one of the editions of their fan club newsletter, The Morning Sun, gave the answer to this great question! Here's what it says the Morse Code translates into:

From Alfred, heed thy sharpened ear,
A message we do bring,
Starship appears upon our sphere,
Through London's sky come spring.

The mystery is solved..... or is it? What do you think?
