Bjorn Ulvaeus does not know if ABBA Voyage will continue if one of his bandmates dies.
The influential pop group - completed by Anni-Frid Lyngstad, 79, Benny Andersson, 78, and Agnetha Faltskog, 75, - reunited in the form of digital "Abba-tars" in 2022, and have played their hit tracks to over three million people since the virtual concert began in May that year.
