This holiday season, there are many ways to celebrate the coming 50th anniversary of the Swedish quartet’s triumph at Eurovision.

For Abba fans, 2024 will mark a major milestone: 50 years since the Swedish quartet of Benny Andersson, Anni-Frid Lyngstad, Agnetha Faltskog and Bjorn Ulvaeus won Eurovision and went on to global superstardom with hits such as “Mamma Mia,” “Super Trouper” and “Dancing Queen.”

And since Eurovision — the exuberantly kitsch annual song contest organized by the European Broadcasting Union since 1956 — is to be held next year in Malmo, Sweden, there is sure to be some kind of tribute.

“A half a century ago we stood on the stage thinking, ‘Oh, maybe we will end up at No. 6 and they will notice us in Germany and maybe even in England,” Mr. Ulvaeus said with a chuckle during a video call. “I still remember that moment when I woke up at four in the morning afterwards and then in the silence, it sort of sunk in that maybe this is the start of something big.”

Tickets to the nine live shows to be held in Malmo during Eurovision week haven’t gone on sale yet, but there are many other ways to shop Abba this holiday season — several of them in the Swedish capital, Stockholm.
