Alle Jahre wieder - Weihnachten mit dem Bundespräsidenten = Every Year Again - Christmas with the Federal President

Frida and Jon Lord performed The Sun Will Shine Again and The Christmas Experiment (which was a compilation of music and Christmas songs with Jon Lord, a choir and an orchestra).

Frida's apparently live singing of the first verse of the popular hymn In The Bleak Mid Winter (as part of The Christmas Experiment) was actually pre-recorded in a studio.

According to the ZDF web-site, Frida apparently decided to lend her voice to The Christmas Experiment spontaneously.  It was originally envisaged as an instrumental piece.

Frida joined all the other performers on the show at the end and joined them for a German Christmas Song.

After the recording of the show, there was a reception at the Town Hall. Both Frida and Jon Lord attended the reception and gave autographs.
