One of my favorite hymns as I was growing up—“Fairest Lord Jesus.” The melody is known as “The Crusaders’ Hymn” and is quite old. I learned to whistle listening to my father who would sometimes whistle as he worked. There is an old bit of folklore that claims women shouldn’t whistle—i.e., “A whistling woman and a crowing hen always come to no good end.” But I don’t believe it.
