Meaning...

Do you remember this song:

"Summer has come and passed
The innocent can never last
wake me up when September ends

like my father's come to pass..."

Well, What the heck does "like my father's come to pass" mean?
I asked 2 american girls (very hot indeed), and they didn't know for sure...

I think "father's" is a contraction of "father has" and "to pass" is used to mean "to die".

I sort of thought there was a noun missing there.

That is to say that "my father's" would be replacing "my father's [something]" that happened.

That doesn't help much, and I could be wrong.

I think you are right about "father has" but "has come to pass" means "has happened". I think this is just a reflection on first seeing the aging process then experiencing it.
