A Christmas Mash-up

I've taken the Christmas Carol's "Angels we have heard on high" and "Gdy się Chrystus rodzi" (a Polish Christmas Carol which translates as "When Jesus is being born").  I wrote two variations on this Polish Carol last year and you can find them here to become more familiar (if you want):

There was some confusion in that thread about which Carol I was actually working on (LoL) owing to the fact that both of these Carol's prominently feature the Latin lyrics "Gloria in excelsis Deo".  But that was basically the inspiration for putting them together in this mash-up.  I painstakingly entered multiple stanzas of the Polish, English and Latin lyrics into the pdf score with all the correct accent marks and whatnot so let me know if it's clear!  Thanks for listening and comments, suggestions, critiques or just observations are always welcome!  Merry Christmas and I hope you enjoy listening!  ☃️
