Carol of the Bells

The wiki bit : Carol of the Bells" is a popular Christmas carol, which is based on the Ukrainian New Year's song "Shchedryk". The music for the carol comes from the song written by the Ukrainian composer Mykola Leontovych in or before 1916; the English-language lyrics were written in 1936 by American composer of Ukrainian origin Peter Wilhousky.

A generation know it from the film Hole Alone with John Williams version of the piece. 

I associate it with our short time in Spain when the staff choir sang it beautifully in the Christmas Concert of 2019.
