Members of the Swedish group ABBA are seen on a display during a Voyage event at Grona Lund, Stockholm, on September 2.
The band is delaying the release of a promotional video after two people died and one was injured at a tribute concert near Stockholm on Tuesday.
None of the victims have been identified, but the BBC cites police as saying the man was in his 80s and the man he fatally hit was in his 60s.
The concert venue said in a statement that it was “shocked by the tragic event” and sending thoughts to the victims and their loved ones, and offered counseling and grief resources for those affected.
MT Live AB, the event company behind the tribute tour, said in a Wednesday Facebook post that they still did not know the details behind the accident.
The real ABBA, meanwhile, is set to release their ninth and final studio album on Friday.
