Lots of hymnals have Hudson's "At the Cross" version of "Alas! and did my Savior bleed?" But there are a few other refrains for this hymn out there (I see two of them, but not the one I'm looking for info on, in the database).
The one I'm really looking for, though, doesn't seem to be in the database. It goes "He loves me, he loves me, he loves me this I know. He gave himself to die for me, because he loves me so!" It is found on pp. 32-33 of the United Methodist Native American worship supplement Voices. The tune is apparently used for a Choctaw hymn beginning "Ne-tahk ish-tah-e-yo-pik-muh-no", though it doesn't scan quite right. Voices says only "MUSIC: Anon."
I don't see a way to search for specific first lines of refrains. Am I missing something?
