We sang ‘Hail Redeemer, King Divine’, and ‘Christ is our King, let the Whole World Rejoice’, which is one of Estelle Wight’s better offerings. You could also have had ‘Majesty’, ‘O Worship the King’, ‘The Servant King’, ‘The King of Love my Shepherd is’, ‘Crown Him with Many Crowns’, ‘The Head that Once was Crowned with Thorns’, ‘Christus Vincit’, etc.
