Björn wrote a book exclusively for ABBA - The Museum called Pop Story, illustrated by Ola Skogäng.

The book, intended for children fro 5-10 years old tells the story of four young, talented people in the late 60s, who met and formed one of world’s bestselling pop groups of all time, ABBA, and wrote Swedish pop history. Published by Fri Tanke, the book was available in English and Swedish and was sold exclusively at ABBA The Museum and via the museum’s web-shop. All royalties on sales went to Barncancerfonden (The Swedish Childhood Cancer Foundation).

In a press release Björn said, “My little 6-year old granddaughter had so many questions!   As we walked through the ABBA museum she saw pictures of me wherever she turned. Dressed in strange clothes and without a beard. To her, it was weird that grandfather had been through so much and why was he being photographed all the time. “Granddad, what’s a pop group?” she asked me."

Björn recorded a short video introduction to the book by reading a few lines.
