Liland,
No fair, you had to have gotten your hymnals out & taken the whole night finding ever single favorite.

Foundation is a good tune for your Christmas breakfast hymn, but have you tried it with Adestes Fideles? The contrast of a tune we connect with Christmas being with Easter words would be really interesting.

I'm going to disagree about Wondrous Love & Captain Kidd being the same tune. They are the same meter. A meter so unique that it's known as Kidd meter. The stresses in it, especially the repeated 4 syllable phrases: Oh my soul, oh my soul; He set sail, he set sail, tend to overwhealm the actual tune. At least the tune I've heard for Captain Kidd is quite different from Wondrous Love.

The Trumpet is lots harder to sing than Diadem. I can't imagine a church congregation actually observing rests and without them I don't think it will work.

Did you realize the Martyrdom you do with Alas, and did my Saviour Bleed is the same as Sacred Throne in Sacred Harp? I was so surprised when I realized I'd been singing it all my life.

I have to add to all these wonderful lists:
Jesus Lover of my Soul. The Episcopal church uses a Welsh tune, I think, which I like fine. But I love S.B. Marsh's Martin (Martyn) with it mostly because that's the tune I grew up on.

Thee will I love my strength my tower is a german hymn translated by one of the Wesleys. Years ago my choir director found it in an old English Methodist hymnal with a tune I really liked with it. I've seen it with other tunes (IVCF hymnal comes to mind) that just did not work as well for me. There's also a Catherine Winkworth translation & much as I like her generally I think this version better.

Gotta go. As a friend of mine likes to sign
