I sure do.
Benny was always a big fan of folk music, and after ABBA he collaborated with a group of Swedish folk musicians called Orsa Spelmän. They enjoyed it so much that they decided to start a band, which became Benny Anderssons Orkester. They invited other musicians, including Helen Sjöholm, the star of Benny's and Björn's musical "Kristina från Duvemåla" and she became their lead singer. Later Tommy Körberg, another big musical star here, joined as well. (He originated the role of Anatoly in "Chess" in London)
The band started in 2001 and immediately became very popular in Sweden. Most of the musicians have other jobs, many in theatrical orchestras in Stockholm, and BAO (as it's called) is a sideproject for them. They usually come together during the summer and go on tour and attract huge crowds.
So far they've released 10 albums and all but one have reached the top 5 in the Swedish charts, the one who missed peaked at #6. They've also had five #1s on the radio chart Svensktoppen, and one of their songs, "Du är min man" stayed on the chart for 278 weeks and spent 65 of those at #1.
This is probably the most ABBA-like of the songs Benny and Björn (who writes the lyrics, but is otherwise not a member of the band) have written for BAO.
And here with English lyrics.
