“September” is a joyful, disco-funk anthem released by Earth, Wind & Fire in 1978. Written by Maurice White, Allee Willis, and Al McKay, the song features infectious rhythms, vibrant horns, and the iconic opening line “Do you remember the 21st night of September?” Its upbeat energy and celebratory spirit have made it a timeless party favorite and a staple of pop culture. Decades later, “September” continues to bring people to the dance floor with its irresistible groove and feel-good vibe.
