one year ago, when I was wondering what to play as a postlude for Gaudete Sunday, someone suggested a piece (I forget the composer) based on "O Come Divine Messiah." I discovered it too late, yet realized how cool it was, and thought "oh, I guess I could play it next year...but next year is so far away! The world will probably like have come to an end by then!"
and here we are.
It's "next year."
And I can play "Venez, Divin Messie" as a perfect postlude!
