Is the song Ukrainian Bell Carol in the public domain?

Since the Ukranian Bell Carol was performed in the US prior to 1923, it should be in the public domain. However, certain arrangements of it may still be protected, for example the common English SATB setting by Peter Wilhousky, or David Foster's recent "new age" version, among many others. Sound recordings of the song (in any version) would also be protected. Cornell University maintains a very fine chart for reference (see link below).
