Additional comments and sources
On the 7"-single "Glussi Christmas",Icelandic singer Stafraenn Hakon covered "Last Christmas",originally by Wham!
He gave it the new title "Siöustu Jöl",but it's sang in English.
For more info on the single,see my topic:
Groeten uit Zeebrugge.
PS : I think this version could be used as a Christmas-song in Twin Peaks!! Really great cover!
