The appearing with Agnetha was Jonas Bergström. He was a Swedish
actor they picked from a Stockholm actors' agency catalogue.
The fantastic bridge is the Årsta bridge in south west Stockholm.
You can get there by train ("pendeltåg") going to Västerhaninge/Nynäshamn/Södertälje.
To get to Tumba Railway Station you have to take the train to Södertälje.
(The train on the bridge goes in wrong direction. Agnetha is waiting on
Tumba station (in southern part of Stockholm) and goes to the city. The
train goes from the north to the south i.e. from the city to Tumba.
The PROMO was directed Kjell-Åke Andersson and Kjell Sundvall.
