"You guys, we have to talk about yesterday's AMAZING night at Berns I had the pleasure and honor to be part of!
Björn and Benny celebrated thus their common 100 years in the industry with a big party with all my colleagues, musicians, tour leaders, etc. that they have worked with over the years!
It was me and Lena invited, because we were part of ”Önskekören” that Björn and Benny set up in the 1980's when we sang their beautiful singing "Klinga mina klockor"
Benny welcomed us (even Björn) and then could the party begin!
Loved Peter and Oscar !
Many of us artists who were there, surprised even jubilar are to perform at the party. Me and Lena did a rocking version of Abbas Hole in your soul that made the entire audience to stand up and dance with! smile emoticon:-) Gorgeous Helen Sjöholm tore off a beautiful number from CHESS!
Comfortable Kalle Moraeus played with her Orsa fiddler plays both during and after dinner!
Fine Vicky and Barbro! Unquestioned guests!
Also met Rolf Skoglund who I played against in my very first TV role when I was 4 years old!:-)
Tomas Ledin with sweet Görel Hanser and Clabbe which together had done a fantastic job of controlling up all night!
I had the legendary Harpo at the table!
Ledin and Glenmark ran an Abba song ..
... Just like Jerry Williams!
But of course the highlight of the evening when Björn and Benny got up themselves on stage and ran Does Your Mother Know!
Though just when everyone thought it was over, so it came as topping it all ...!
Then stepped two beautiful women named Frida and Agnetha onto the stage and started to sing ABBA's old "The Way Old Friends Do", and it was so beautiful that you just wanted to cry ...!
When the first chorus came we stepped girls who had been singing before, also on the scene and put in the correct running behind the girls. Then, when Björn and Benny joined probably was not a single dry eye inside Berns ....!
Suddenly it was realized that this is actually ABBA on stage and singing right now ... !!
What a finish! What a night!!!
We ended the evening with all of us together on Frida's invitation sang Frida's favorite snaps show (and also my mom and dad's) " Now all good friends Cheers!"smile emoticon:-)
So honor to sing fellow and - these two beautiful and uber talented legends, which despite its huge success yet so genuinely cute and natural when you meet them!
An evening to remember a long time ....! ♥
Thanks Björn and Benny for letting us be a part of it. ♥"
) Considering the last time we heard that song live by them it was over 30 years ago. 
Well worth the wait.
