Early Breakfast with Jenni Falconer 4am - 6am
They pledged it would never happen so we were not expecting it. Last night, all four members of ABBA hit the stage to sing together one more time. It was a truly Super Trooper moment.
The gang hit the stage at a private party at the Stockholm's Berns Hotel to celebrate the 50th anniversary of the day when ABBA's songwriters, Bjorn Ulvaeus and Benny Andersson met for the first time.
Later on that night, just when revellers were getting ready to wrap up the part, the other half of ABBA, Agnetha Faltskog and Anni-Frid Lyngstad, rocked up on stage too to perform the 1980 hit Me and I - performing together for the first time in 30 years.
Not sure you remember that number? Relive it below:
"It was absolutely amazing. A lot of emotions,” singer Anni-Frid Lyngstad told Sweden's Expressen newspaper. "We've made this journey throughout our history. Benny and Bjorn in particular. It’s been very nostalgic."
Fans have taken to Twitter to profess their love for the group, including actor and comedian Matt Lucas!

Agnetha & Frida from ABBA apparently SANG LIVE ON STAGE 'The Way Old Friends Do' with their former ABBA husbands tonight in Sweden— Steven Moore (@MilkySteve) June 6, 2016
We've been trawling through the internet for video evidence but unfortunately we can't find it anywhere! Hopefully this won't be the last time they perform together. Perhaps a reunion tour is on the cards?
