ABBA? Maybe They Were Swedish?

Another sequence of photographs... this time of my "Belgian" kids (if truth be known, I was probably the same age as they were, so perhaps I should call them "contemporaries"). I can't remember following them per se, but I must have. Maybe we just had the same agenda for the afternoon. The pictures on the right (all from a really mundane "rear" perspective) were taken after I had the "correct" shot in the can... but how was I to know?

The original picture is here.

Note again: the superb Nikon 50mm prime lens!
