Today’s the day when your neighbors can think you’re crazy for blasting the hit “September” from the seminal funk band Earth, Wind & Fire. The song lyrics references the night of September 21st as something you need to pay attention, too, and there’s a whole story behind it.

It’s their entire brand now. “Do you remember…”

And we’re not complaining. This song is the jam.
