Brian D'Arcy starts a series of programmes looking at the Beatitudes - the blessings of Jesus. He explores what they mean and what promises they hold. This week, Blessed are those who mourn. This week's featured choir is the Sirenian Singers recorded at the church of St Mary the Virgin in Wrexham. The musical director is Jean Stanley Jones and the organist is Graham Eccles. Hymns include The King of love my shepherd is; Great is thy faithfulness and I vow to thee my country.
