I need help finding a mixed Chorus, Choir, or Chorale Christmas album from the 40's, 50's, or 60's that's on YouTube! Each track on the album is a medley instead of an individual song, practically each track opened with Caroling Caroling, Sing We Noel, Sing We Now of Christmas, Master's In The Hall, or Now Is The Caroling Season and the album is named after that carol and one of the songs or the last song of the last track is Sleigh Ride! There is an Amen Cadence at the end of O come, all ye faithful in this album!
The pdf download of the dissertation from A History Of The Plagal-Amen Cadence references a number of hymns with plagal cadence. I haven't gone through the whole text but this seems to be a good starting point to identify the hymns you may want, which were originally composed with the cadance, and then try to track down a recording.
I don't know of any specific albums sung in English containing this cadence (I don't have any Latin recordings to hand).
I suspect that you may have to create your own recordings.
