I haven't listened to Bill's version of the tune (Whitby Fisherman) yet, but I'm wondering if he simply uses the refrain; this would possibly account in part for your (Joe's) description, "The tune ... is here (click) at the Cyber Hymnal, but it doesn't sound quite like Bill sings it. He sings it slower and more softly, and his rendition of the tune is a bit different." The original text is what we hymnal-editor types call "87.87 w/ Refrain", while Bill's text is "87.87 D w/ Refrain".
