1970s electronic music video set in snow

I'm trying to find a really old electronic song I remember from my childhood. I have tried providing all the information I can remember:
- it is probably from mid-late 70s, since that is when I remember first seeing the music video
- it is electronica and maybe a bit disco
- i don't think there is any singing/lyrics, but that might be my bad memory
- the main memory is the video clip - the band was playing in a sunny snow/ice wasteland. Almost like the stage was in the middle of a glacier.
- it is probably European, but maybe I only think that because of the snow
- it was probably a big hit, since they showed it on Australian TV back in the 70s. I seem to remember seeing it on TV together with "popcorn", although that is an earlier 70s song.

I have tried searching for music videos featuring ice or snow but with no luck so far.

Just a try...: nn my memories I always combine "Popcorn" with "Magic fly"; it was a big hit in Europe in the mid 70ies

Could it be The Shadows - Apache?

Try this song:

"Fanfare For The Common Man" by Emerson, Lake & Palmer

My wild guess is "Hocus Pocus" by Focus (Dutch band) from 1971.
It had no real lyrics, just some brief intermittent "vocalizations".

A more electronic instrumental song would be Alan Parsons', "I, Robot" (1977). However, there never was an Alan Parsons "group" (to make a video); just Alan, Eric Woolfson and various studio musicians.
Not helpful, just thinking out loud...
