Dutch beer brand Grolsch jams out Christmas music with the Swingtop Philharmonic Orchestra, a troupe made up of some of the world's leading musicians and sound engineers who play exclusively on instruments made from Grolsch Swingtop bottles.

A re-imagined version of the Christmas favourite by Ernst Anschütz has been arranged by composer Ross Power and is led by conductor Thomas Blunt, seven percussionists, woodwind players and a timpanist.
