Not sure how you managed to create this but its very good and proof that if the urge to do so was there, a release of 1977 live material could be achieved. I know some of your footage is from 'ABBA - The Movie' but you have some shots I've never seen before. Well done.
I think we will might see the full version of some their performances in this concert, since another version of ABBA: The Movie (with yet to be seen extra video materials) will be released on September this year, but will be only shown on limited teritories (i.e. Europe).
