Christmas song where they are singing in the desert.?

Its a christmas song from the late 70s early 80s I think. The main guy has long hair and the video is set in a desert. Please can I have the title so I can get this song.

It could be the classic "I Believe in Father Christmas" by Greg Lake.
(My favourite Christmas song of all time, by the way!)
