According to Benny, at the ABBA time, he couldn't stand no one who was not able to do anything with him, including traveling around the world, while he was working. Because of this, "it was wonderful to share everything with Frida".
I realized that everything was, indeed, everything. Take a look at the pictures below and you will understand what I mean.
Hummm, Frida's wearing a very nice coat, isn't?
Ah, but who is wearing this coat now?
Benny liked so much this coat that he wore it on One Man, One Woman music clip
The question now is: Whose coat was that, Benny's or Frida's?
Or did they buy it for both of them?
It doesn't matter - for them it was wonderful to share everything!
