This was one of the four TV specials made around this time. Some of the clips, introductions and even guests mixed and matched in the various programmes:

1. ABBA in Switzerland
2. Boney M in Switzerland
3. Disco in the Snow and Disco in the Snow Part II
4. ABBA Snowtime/Christmas Snowtime/Snowtime Special/Christmas Snowtime Special.

Disco in the Snow Part II was introduced by Leo Sayer with Boney M, The Jacksons, Curtis Mayfield, Leif Garrett, Amii Stewart, Bonnie Tyler, The Raes, Rozalind Keane, Patrick Juvet and Eruption.

Agnetha and Frida appeared briefly introducing Ted Gärdestad performing Take Me Back To Hollywood.  This was presumably also shown in the Swedish broadcast of ABBA in Switzerland because the clip has Swedish subtitles. (Personal note: I must have watched this programme as a kid because the Ted song stuck in my head for years afterwards until I learned more about ABBA and their Polar label-mate!).

Part I (Disco in the Snow) of this show included The Jacksons performing Shake Your Body (Down to the Ground) in front of a large, rather familiar snowman!  See it here - if the link works!

Frida: Thank you. There was a time when it seemed that the only name people knew from Sweden was ABBA.
Agnetha: It was a bit embarrassing!
Frida: It was lovely really, but it's a relief and a pleasure to welcome from Sweden ...
Agnetha and Frida: Ted Gärdestad!
