A 21-second clip with ABBA congratulating Disco - and host Ilja Richter - on their 100th show.

There were no close-ups of Frida or Benny. They spoke in German.

Frida's shiny face! She also does not look at all happy.

ABBA: Hallo friends, Hallo Ilja (Disco's host)
Björn: We would have loved to have come along ourselves to celebrate Disco's 100th show
Agnetha: Many congratulations and best wishes to Disco and all your fans from Agnetha
Benny: Benny
Björn: Björn
Frida: And Frida
