Those words are spoken at the beginning of the 1985 song "L'Affaire Dumoutier" by Montreal band The Box. If you're not Canadian and/or don't remember the 80s, then you're probably unfamiliar with the song -- and even if you are a Canadian who remembers the 80s, there's no guarantee that you remember the song. I had a vague recollection of it, and thought it had a trippy video, and hence was pleased to have recently tracked that song down.
Anyway, that song got me wondering: what are the most famous examples of songs that mention a specific date? I'm thinking specifically of "name of month" + "number" -- there are plenty of songs containing the words "Halloween" or "Christmas" or "New Year's Day", but fewer that say "October 31st" or "December 25th" or "January 1st".
The three best-known examples that occur to me are:
"Pride (In the Name of Love)" by U2 (Early morning / April 4 / Shot rings out in the Memphis sky)
"September" by Earth Wind And Fire (Do you remember / The 21st night of September)
"Saturday In The Park" by Chicago (Saturday in the park / Think it was the 4th of July)
