ABBA, the legendary pop band, again set the stage on fire on Sunday, June 5. To celebrate the band’s 50th anniversary, the members reunited to perform together on stage that day. After a lengthy hiatus of 30 years, the Swedish group has made an elating comeback at Berns Salonger in downtown Stockholm!

The group comprises four members: Agnetha Faltskog, 66, Björn Ulvaeus, 71, Benny Andersson, 69, and Anni-Frid (Frida) Lyngstad, 70.

ABBA songstresses Frida and Agentha started to perform their 1980 song “Me and I,” dedicating it to Ulvaeus and Andersson. Soon, the male half of the group jumped on stage at the end of the song to cap the grand reunion.

It is rare to spot the members all together. Earlier this year, ABBA reunited for the restaurant opening of “Mamma Mia! The Party in Stockholm.” It was a get-together where the members were photographed together for the first time since 2008.

Here are five fun facts about the beloved band every fan should know!

  1. One of the most thriving recording acts of all time, ABBA topped the charts worldwide from 1974 to 1982.  It was the first band  from a non-English-speaking country to be in the charts of English-speaking countries, including the UK, Ireland, Canada and Australia
  2. In 2010, news came that ABBA would be inducted into the Rock and Roll Hall of Fame. However, Andersson declared its impossibility due to many reasons which included Agentha’s refusal to fly, reported Rollingstone.
  3. The singers were also spouses in real life. However, they split. Andersson and Lyngstad tied the knot but separated in 1981. Ulvaeus and Faltskog got married, but in 1980, the marriage ended in a divorce. They share two children, Linda, 43, and Peter, 38. All the four artistes have since then moved on and remarried other people. This reunion is turning all he more special as the two former couples are coming together to form ABBA.
  4. ABBA promoted many products including baby food. In 1973, the disco group promoted Semper’s baby food, and it was Björn and Agnetha’s daughter Linda who debuted in this ad.
  5. On St Valentine’s Day 1977, just 10 days after the release of their single “Knowing Me, Knowing You”, ABBA held its first concerts in the UK and it included two dates at the London venue. The show was so much in demand that over three and a half million applications for the 12,000 seats were received through mail, reported Buzzfeed.
