Footage of Benny, Björn and Michael B Tretow in the studio - looks like the Chess era.

The footage was broadcast on The Winner Takes It All - The ABBA Story, but where is it from originally (ie. what was it filmed for - could the clip perhaps come from Historien om ABBA (The story of ABBA), broadcast on SVT2 April 30 1984 which is apparently available in the Swedish media database?
