This is fascinating. Where in "Indecent" were the lyrics used? Were they sung with Ilse Weber's Wiegala melody?

I will be giving the pre-concert lecture to Princeton Pro-Musica's performance of Annelies by James Whitbourn, on March 15, 2020. I would like to know as much as I can about this melody. Was the melody pre-existing and new lyrics ascribed as was common during the period?
