For Björn's 80th Birthday, the ABBA Intermezzo International Fan Club organised a book to be presented to him which included personal messages and photos from the fans.

At some point, the book was sent or given to Björn and he sent a thank you video even saying it was one of his best birthday presents.  

He said, "I just wanted to tell you all in ABBA Intermezzo Fan Club how moved and happy I was to see this fantastic book that you've all put together. And I realise that a LOT of effort has gone into this project.  So … it was one of my best birthday presents, I can tell you that.  So thank you very much."
