In the early 80s, one of the big bands on the Swedish music scene was Adolphson & Falk. A lot of their early stuff covered space, technology, radios, and astronomy (they met during their military service at the Swedish agency for signals intelligence). This is their breakthrough song “Blinkar blå” in English translation.
As far as I know they have never been a part of or encountered sf fandom, but this is true found filk.
