A childhood belief about songs

i've grown up listening to the beatles, and thus had some interesting beleifs relating to their songs and music, etc.
i always wanted to listen to the beatles when we were in the car, and on one of the songs they use a shaker (looks like an egg and sounds kind of like a maraca). i assumed that there were five beatles. the fifth one played the maracas.
i also thought that the lyrics to lucy in the sky with diamonds went "the girl with colaidis goes by". i thought colaidis was some sort of horrible disease, and when i got older figured it was an STD, and was too embarassed to ask my parents (thank god or they would have wondered about me). i only found out just recently that it goes "the girl with kaleidoscope eyes" when i got so curious i had to look up the lyrics so i knew how to spell colaidis to look it up in the dictionary!
