The Genius of Paul McCartney

So, the other day I was driving, singing along with the radio to Paul McCartney & Wings' "Jet." I thought, "boy, you know what, this is a great song!" Then after singing along with the lyrics some more, I thought, "I have absolutely no idea what this song is about." So I turned to Wikipedia, and they said that the song was about a labrador puppy Paul owned named "Jet." What? That made the song make even less sense than before. Viz. the lyrics, according to the liner notes:

Jet! Jet! Jet!
I can almost remember their funny faces
That time you told 'em you were going to marrying soon
And Jet,
I thought the only lonely place was the moon
Jet! Oo Jet! Oo

Jet! Was your father as bold as a sergeant major?
Well how come he told you that you were hardly old enough yet?
And Jet,
I thought the major was a lady suffragette
Jet! Oo Jet! Oo

Ah, mater, want Jet to always love me?
Ah, mater, want Jet to always love me?
Ah, mater, much later

And Jet,
I thought the major was a little lady suffragette
Jet! Oo Jet! Oo

Ah, mater, want Jet to always love me?
Ah, mater, want Jet to always love me?
Ah, mater, much later

Jet! With the wind in your hair of a thousand laces
Climb on the back and we'll go for a ride in the sky
And Jet!
I thought the major was a little lady suffragette
Jet! Oo Jet! Oo

And Jet,
You know I thought you was a little lady suffragette
Jet! Oo
A little lady. My little lady, yes!

In other words, as far as I can tell it's collection of words that sounded good together when he shouted "Jet!" It's meaningless. And yet it's a great song. That's the genius of Paul McCartney.

Update: corrected the lyrics to the liner notes' version
