Songs Everlasting - Series 2 - Deck the Halls

Bryn Terfel explores classic Christmas songs and tries to find out what it is that makes some of them them so popular. Bryn speaks to composers and scholars about the carol Deck the Halls: how it evolved from an ancient Welsh dance tune, the origination of the words, its association with New Year and why it has become a favourite for recording artists of all persuasions.
