In English, the song is known as "O Sacred Head, Sore Wounded" or "O Sacred Head, Surrounded." 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. Presumably, it was written first in Latin, but I haven't heard anything by German and English versions attached to this tune.
Tom Glazer used this tune for "Because All Men Are Brothers," recorded by Peter, Paul and Mary on the See What Tomorrow Brings album.
