EarthWindandFireVEVO: Billboard Hot 100 song September by Earth, Wind and Fire.
September 21?
"We went through all the dates: 'Do you remember the first, the second, the third, the fourth ... ' and the one that just felt the best was the 21st ... I constantly have people coming up to me and they get so excited to know what the significance was. And there is no significance beyond it just sang better than any of the other dates. So ... sorry!"
-- Alle Willis
