Two Swedish musicians, a folk singer & the double-bass player: 1. Dan Berglund is an Swedish folk singer and guitarist, born in Helsinki, Finland in 1954. In the 70's he was affiliated with the Swedish Marxist-Leninist communist party (KPML(r)), but in '79 he turned his back on the party. He is most known for his album "En j?rnarbetares visor", released in 1975. He is still somewhat active and was again popularized when the Swedish left-wing punk/rock band EAK had at least one cover of his songs on each of their releases from the mid-90's to the last in 2000.
