News rushes of ABBA going on a boat trip. Frida's body language is especially bored with the press. Some footage has sound, some doesn't.
This behind-the-scenes footage has not been broadcast officially. It's found it's way into the fan network somehow. Most unused footage is usually junked and the only footage to be filed is that included in the story that finally airs. Even stuff of this vintage has a high chance of not surviving. Thanks to the huge hype surrounding ABBA's visit, all material was probably archived for stock usage.
Thanks to Philip Muytjens, Paul Russell, JS, Magda, Matti Crocker and Ian Cole for information.
