In this cosy November edition of Upbeats, JJ and Haz discuss why choral music goes well with hot chocolate, the effect of conductor Harry Christophers' flowing locks, the music of Gjeilo (not J Lo), and the difference between female sopranos and boy trebles. The piece explored this time is Herbert Howells' 'A Spotless Rose', in time for the concert at St David's Hall by The Sixteen.
