Renowned music journalist Jan Gradvall gained unparalleled access to ABBA after doing a story for a Swedish newspaper in 2013 and subsequently gaining the group’s trust.
Since then, Jan has grown intimately familiar with the 70s pop supergroup and put a decade of deep research into his new offering The Book of Abba: Melancholy Undercover, for which he also interviewed each of the band members exclusively.
He joins Jim to chat about one of the world's most famously private bands.
