This is a festive mix of sing-along carols, orchestral showpieces and opera highlights performed by the Glyndebourne Chorus and Glyndebourne Sinfonia. Look out for the hour-long Chilled Christmas Celebration (Dec 14) in which the audience is welcome to move about the auditorium and – normally a big no-no – chat about the performance while it’s in progress.
