Andrew Motyka and I typeset the versions for the 2014 Epiphany Proclamation for your use on the Feast of the Epiphany. This is one of the optional (but cool) traditions of the Roman Rite!
There are two versions in the file, depending on which day your Diocese celebrates the Ascension, and the file also includes both modern notation and chant notation (neumes).
Just one of the many great things coming out of the CMAA forum!

Additionally, Veronica Brandt has provided us for an edition for use in the Extraordinary Form of the Roman Rite HERE.
