It’s in Danish, from the 1984 movie Midt Om Natten. You must read the subtitles and watch the video to appreciate it:

According to Wikipedia, Kim Larsen has had a number of successful album releases throughout the 80s, 90s and 00s and is possibly the most successful artist in Danish popular music history.

The New York Times review of the movie says: “Bohemians Arnold (Erik Clausen) and Benny (Kim Larsen), unemployed plumbers who earn their livelihood moonlighting, create their own little anarchic world in an abandoned factory. This gentle satire owed its fleeting popularity to its stars, cavern-mouthed pop star Larsen and comedian Clausen, the latter especially known for his satirical comments on the Danish establishment in particular and bureaucracy in general. A throwback to the wild and woolly 1968 Summer of Love, Midt om Natten was slightly anachronistic already when it premiered.”

Here is a catchy 1986 song by Larsen called Jutlandia. The Jutlandia served as a hospital ship in the Korean War.
