When David Heard (Tomkins) The Gesualdo Six at Ely Cathedral

Thomas Tomkins poignant 'When David Heard' uses the text of 2 Samuel 18:33. It is sung here in the Lady Chapel of Ely Cathedral, by The Gesualdo Six, who are taking part in Ely Cathedral's #LiveHolyWeek campaign.
When David heard that Absalom was slain
He went up into his chamber over the gate and wept,
and thus he said:
my son, my son, O Absalom my son,
would God I had died for thee!
