The form of this service varies throughout the month - the normal pattern is as below, but this may change to accommodate festivals and other special occasions.

The first and third Sundays of the month are a spoken service of Evening Prayer.
On the Second Sunday, it is Compline, sung to plainchant by the gentlemen of the choir. This is a short service of around 20 minutes.
The Fourth Sunday is a full Choral Evensong with the choir (including Magnificat and Nunc Dimittis setting, and an Anthem).
Where there is a fifth Sunday in the month, there is no evening service at the Parish church - instead a Service of Evensong takes place in one of the two associated churches in the Parish - Little Hampden and St Mary's Ballenger.

Please see the church Facebook page and website for the latest details of specific services - at present, these services will not be available online.
