"September" is a date that became a feeling. Earth Wind & Fire recorded it in 1978 as a celebration of memory, a song that picks a specific day and fills it with so much joy that the date stops mattering. The lyrics do not explain what happened on the 21st of September. They do not need to. The feeling is the story. Maurice White understood that the most powerful memories are not the ones you can describe. They are the ones you can only dance to.
