For all you who can't get the version from the Lutheran Hymnal to scan, I'll just say you'll have to take my word for it. I've done since a child, so for me there's no problem. I think the key is that the slurs come in different places in the different versions, but I don't really have the time to sit down & do the comparisons. Maybe if you listen to the midi it will make sense. http://www.lutheran-hymnal.com/online/tlh-102.midLiland, I did know it wasn't you who asked, I just started combining all my comments. The hymnal I was referring to is the one used by the Missouri Synod Lutherans. It is just called The Lutheran Hymnal. It was published in the 1940's & some churches still use it. It's a good source for German chorales but weak on anything really American in origin, except for a few Lowell Mason hymns. Follow my link for the texts
Looking at other hymnals, I can only say there were a whole lot of variants on the translations used until early in the 20th cent. the Oakeley seems to have won out.
Foundation is called Bellevue in The Sacred Harp & is an American Folk hymn. It's 1844 arrangement is attributed to Z. Chambless. A fair number of southern based churches picked up the shape note tunes & rearranged them in the early part of this century. Not so much shape note aware, as popular hymn tunes still in use. If you want to find early non-shape versions try to find Methodist, Presbyterian, Baptists in their southern branches as well as 7th day Adventist and Church of Christ. I have a Church of Christ hymnal from the 30's that has both Foundation & Adestes Fideles with How firm a foundation. I found both the Episcopal and Lutheran hymnals of the 1940's used completely different tunes. Episcopal used Lyons & The Lutheran Hymnal one that may have been composed for it as it's dated 1930's by someone with a German name.
