Danish band Gnags in 2006, singing one of their hits from the seventies. This band was founded by the singer in 1966... Fucking hell, I hope I have that kind of energy when I'm in my mid-fifties! (In fact I'd have loved to have this kind of energy when I was a teenager.)
"Burhøns" means battery hens, hens kept in tiny cages. It's typical of the Socially Responsible pop/rock music from the Danish music scene in the seventies. It's rescued a bit by one line hinting that it's really about humans living like battery hens.
... I was led to another seventies pleasure, this time a vintage performance, Sultans Of Swing.
