Greetings all,
I needed to make a quick handout for my choir for our procession, so I transcribed and combined the two Palm Sunday chants on to one US Letter sheet, and included singable translations (if desired) as well as the psalm verses indicated in the missal for Pueri Hebræorum. (They aren't the best, but they work. We aren't singing them, but I figured this would be more useful if they were included.)

Hope this helps somebody.
