Uhm, it may be me, not the composer who is guilty of the mondegreen. I transcribed it from the CD. (Why is it UK CDs don't include the words?)It sounds most like "waif" or "wave" but given the dialect and that I live in the US, there's plenty of room for error. So go by the sound and not my spelling of it, if you're using dictionaries.
Does that help?
Blessings,
Barbara

P.S. The CD is "Never a Cross Word" by Danny and Joyce McLeod.
