All (old enough) Swedes know this, you may or may not know it: Björn Skifs who is here playing The Arbiter was also the guy who made it to #1 in the US with his (band's) version of Hooked on a Feeling (ooga-chaka ooga ooga ooga-chaka) back in 1974, which was also made somewhat famous again in 2014 with Guardians of the Galaxy.
