I think the tune is even older. It's from a hymn called "O Sacred Head Surrounded" (O Haupt voll Blut und Wunden). My St. Gregory Hymnal says the lyrics were by St. Bernard of Clairvaux (1091-1153), and melody by H.L. Hassler (1600). The hymnal uses Bach's adaptation of the tune.

Then there's "Lover's Concerto," the 1965 hit by the Toys. My Who Wrote That Song? book says words and music were by Sandy Linzer and Denny Randell, but it was based on Bach's "Minuet in G."

Are there others?
