“Ba-dee-ya”: how Earth, Wind & Fire defended nonsense

In the summer of 1978, a young lyricist named Allee Willis walked into an Earth, Wind & Fire session and heard the band playing what would become “September”. In one spot, Maurice White kept singing “ba-dee-ya”. Willis assumed it was a placeholder — a sound holding the seat until a real word arrived.

She spent the whole project trying to replace it. On the final day of recording she gave up being polite and asked directly: what does “ba-dee-ya” actually mean? White answered with a question she would quote for decades — who cares about meaning, if the phrase keeps the groove moving.

Willis said that day taught her the most important lesson of her career: never let the lyric fight the groove. The song came out in November 1978 and became one of the band’s best-selling records. A chorus nobody can translate gets sung in every language the same way.

There is one detail only careful listeners notice: the lyric names the twenty-first night of September, and none of the writers ever explained why. White would only say the date sang well. Sometimes that is the whole reason.
