The organ part is missing; it is likely that brass and percussion parts are also missing.
Lyrics
Splendor and honor and kingly power are yours by right, O Lord our God,
For you created everything that is, and by your will they were created and have their being.
And yours by right, O Lamb that was slain, for with your blood you have redeemed for God,
From every family, language, people, and nation, a kingdom of priests to serve our God.
And so, to him who sits upon the throne, and to Christ the Lamb,
Be worship and praise, dominion and splendor, for ever and for evermore. Alleluia.
