Hey Ernest,
yes they are. (I mean, a Folk-Rock-Pop-Band)
It is a project called "The Berlin Siffle Session". And all members of the band Calm Wizardry are within. But also members of "Worried Men Skiffle Group" from Bielefeld (established 1964) and members of "The Skiffle Revival" (1973-2006). They called it "Berlin" because in this constellation they had done a great gig on Easter this year - in Berlin! It was so succesfull that they decided to make a record.
You can read this on the homepage of Calm Wizardry.
Click on "The Music"
Then there´s a flying man.
Then click on the very right box. It´s the CD "Berlin Skiffle Session".
There you can listen to the songs and get more information about this project.
Greetings,
Winni
