When Earth, Wind & Fire asks, “Do you remember the 21st night of September?” the question has become a yearly ritual. Although the group’s classic single “September” was released on November 18, 1978—not September 21—the date in its opening lyric has made September 21 an unofficial annual celebration of one of popular music’s most joyful records.
Written by Maurice White, Al McKay, and Allee Willis and produced by White, “September” brought together the elements that defined Earth, Wind & Fire at their peak: buoyant rhythm, crisp horns, layered vocal harmonies, funk guitar, and an irresistible singalong refrain. The song appeared as a new track on the compilation The Best of Earth, Wind & Fire, Vol. 1 and became a major hit, reaching No. 1 on Billboard’s R&B chart and No. 8 on the Billboard Hot 100.
Its power lies in how effortlessly it turns musical sophistication into pure celebration. The rhythm feels propulsive without being hurried; the horns answer the vocals like another voice in the conversation; and the famous “ba-dee-ya” hook makes the song instantly communal. Decades later, it remains at home on dance floors, in wedding playlists, at sporting events, and in the annual flood of September 21 social-media posts.
The lyric’s date has long inspired curiosity. For years, White and co-writer Allee Willis suggested that “the 21st” was selected largely because it fit the melody and sounded good when sung. But Marilyn White, Maurice White’s widow, later shared a more personal explanation: September 21 had been the expected due date for their son, Kahbran, who was born early on August 1, 1978. She described hearing the lyric as a private message from White to their family.
Whether listeners embrace the musical explanation, the family story, or both, “September” endures because it makes memory feel like a party. Its opening question does not demand a specific answer. It simply invites everyone to remember the feeling: joy, dancing, love, and a night worth singing about.
