Around Christmas time you always hear the same classic popular songs by Wham, Chris Rea etc. and in the Netherlands there is one popular song by a comedian called ‘Youp van ‘t Hek‘ that gets a lot of air time in the days leading up to Christmas.

It is both a funny and sad song and you can read the lyrics, as well as listen to the song here.
