This is from the U.K. translation of Paschalis Sollemnitatis, the Vatican 1998 “Circular Letter Concerning the Preparation and Celebration of the Easter Feasts,” emphasis mine:
97. Mass is to be celebrated on Easter Day with great solemnity. It is appropriate that the penitential rite on this day take the form of a sprinkling with water blessed at the Vigil, during which the antiphon ‘Vidi aquam’ or some other song of baptismal character should be sung. The entrance steps to the church should also be filled with the same water.
Golly, the antiphon Vidi aquam takes on new meaning with its “I saw water flowing from the temple…”
