The only other thing she mentioned in her discussion that I thought was a bit different from what Waldorf and Sauron said was about ASSEMBLY, the tune we currently use.
In fact, in the preface to the book, she lists the origins to that tune as one of the mysteries that we may never know about our hymnbook."The tune ASSEMBLY was first published in 1844 in a small hymnal designed for use by Latter-day Saint missionaries in New England. It may have been an already existing hymn tune; some believe it may even be HOSANNA, the tune used at the dedication of the Kirtland Temple. To this point, no researcher has uncovered the details of its origin."
Oh, and if you ever get the chance to take this class from Bro. Clyde Williams, it was an awesome class.
