This is another one of the selections in Gather Australia for the Body and Blood of Christ.
Christopher Willcock wrote the tune and used 1 Cor 11:24-25 for the refrain and 1 Tim 3:16 for the verses. The tune drifts from one time signature to another and the third verse has a different tune. This is for a choir.
The text of the refrain is actually the ICEL text based on 1 Cor 11:24-25:
… the proper Communion Antiphon for Holy Thursday (Evening Mass) is “This body will be given for you. This is the cup of the new covenant in my blood; whenever you receive them, do so in remembrance of me” (1 Cor. 11: 24-25).
