Malcolm Proud and Róisín O'Grady have made a slight alteration to the programme for their concert on 15 July.

In place of the Bach trio-sonata in C minor, BWV 526, Malcolm is now playing four settings by the seventeenth-century French composer Nicolas de Grigny of the plainchant hymn Ave maris stella, while Róisín will sing the chant verses between.

With this alteration, England, Germany, Italy and France are all represented in the programme.
