I read Testudo's post and surfed the net in hope to find a broadcast of that concert. I stumbled over this;

J. D. Zelenka - Missa Nativitatis Domini ZWV 8

Oude Lutherse Kerk, Singel 411 (hoek Spui), Amsterdam
In Bern 18.12.2010 this program was played;
Weihnächtliche Kantaten des Dresdner Barock
(Schweizer Erstaufführungen)
J. D. Zelenka:
Missa Nativitatis Domini, ZWV 8 (Fragment): Kyrie, Gloria, Credo
Missa Charitatis, ZWV 10: Sanctus, Agnus Dei
J. D. Heinichen: Pastorale
G. A. Ristori: Motetto pastorale (für Sopran- und Alt-Solo, Frauenchor und Orchester)
G. A. Homilius: Kantate "Ergreifet die Psalter"
Missa Nativitatis Domini ZWV 8 seems popular this Christmas.
Lets hope one of these concerts was recorded and finds its way to youtube
