World-renowned #Dutch conductor and violinist #André_Rieu, together with #Ukrainian-born singer #Anna_Reker, performed the legendary #Ukrainian Christmas carol #Shchedryk (#Carol_of_the_Bells).

It was performed live during the #Johann_Strauss Orchestra concert in #Maastricht, #Netherlands.

As #Rieu admitted, he always thought that #Carol_of_the_Bells was an American Christmas song.
