ABBA have announced that they are pausing promotion of an upcoming show for 24 hours, after two died in a fall at a tribute concert in the group's native Sweden.

The world-famous quartet will release a new album, Voyage, on Friday, 40 years after the group split up.

But on Tuesday night, an 80-year-old man fell seven storeys to his death at a concert hall in Uppsala in a presumed accident, killing another attendee.

The venue north of the Swedish capital Stockholm was to host a tribute show for an audience of around 1,000 called Thank You for the Music, honouring the works of Bjorn Ulvaeus and Benny Andersson, the two male members of ABBA.

"In the light of the tragic news at the tribute concert in Sweden last night, we have decided to hold off on releasing our concert trailer until tomorrow," a post from the ABBA Voyage Twitter account said.

In addition to the release of the new album announced in early September, ABBA are currently building a venue in London that will host a show which includes digitised avatars of the four band members, scheduled for May 2022.

The exact form of these avatars, designed by a special effects company that worked on the Star Wars films, is still shrouded in mystery, but ABBA insist that they will not be mere holograms.

The "ABBAtars" will represent Agnetha Faltskog, Bjorn Ulvaeus, Benny Andersson and Anni-Frid Lyngstad as they looked in 1979.
