Max, Bjorn Ulvaeus was in a Swedish quartet named The Hootenany Singers prior to the ABBA era and was a great fan of the Kingston Trio and Brothers Four.

I met Bjorn (and Benny Andersson) in 2009 at a Carnegie Hall event and spoke to him about the trio. He said he remembered sitting with Bob Shane at a stage performance of Mamma Mia and that Bob told him he was going to make a lot of money from the show.

Now, nearly 40 years after ABBA took a "break", we are getting new music!
