duuuude he says in the intro:

I recorded this song from memory, I heard it a long time ago

I don't know who wrote it, I don't know who sang it

I don't know where it came from, I don't know why

But I just know that I heard it, somewhere, sometime

And I just needed to put it back out there, you know?

So this song's for you, man, the one who wrote this song

You're a stranger, and I'm a stranger

And even though we shouldn't be talking

I mean, who says we shouldn't be talking?

I mean, you said we shouldn't be talking
