Carl Magnus Palm wants to update and re-release his book "The Complete Recording Sessions via Crowdfunding. This means that fans are asked to donate money in order to make and release the book. Why such an approach is chosen remains a big question, but fact is that this book was a groundbreaking book back in the early nineties when ABBA was at the point of a big revival.
Agnetha did not allow Carl Magnus Palm an interview at the time.
