Anthem for the Ascension of our Lord.
The Finzi anthem is the second on this clip and it starts at 3:20.
God is gone up with a triumphant shout:
The Lord with sounding Trumpets’ melodies:
Sing Praise, sing Praise, sing Praise, sing Praises out,
Unto our King sing praise seraphicwise!
Lift up your Heads, ye lasting Doors, they sing,
And let the King of Glory enter in.
Methinks I see Heaven’s sparkling courtiers fly,
In flakes of Glory down him to attend,
And hear Heart-cramping notes of Melody
Surround his Chariot as it did ascend;
Mixing their Music, making ev’ry string
More to enravish as they this tune sing.
