It offers them an opportunity to continue to enjoy singing to a high standard beyond the end of their choristerships. Membership is by invitation only. The choir sings around three times a term, typically at Evensong and Compline in Advent and Lent. Concert work has included Mendelssohn’s Elijah alongside the Cathedral Choirs and St Albans Bach Choir, and performances alongside the King’s Singers and Jethro Tull. At Easter 2018, the choir broadcast Easter Sunday Worship live on BBC Radio 4.
