WHAM!’s LAST CHRISTMAS HAS BEEN REMASTERED IN 4K _ Christmas has arrived early this year, in the form of a 4K remaster of Wham!’s iconic Last Christmas music video. The track was originally released 35 years ago in December 1984, and Sony Music Entertainment has now remastered the original footage in 4K. Those awesome 80's hairstyles are still pristine. George Michael would be proud.
