Hi, Joe:

I went googling for Healey Willan and found the following paragraph in a document dating from the late 1980s, posted in MS Word format.

"In addition to the music provided for these antiphons in the Roman chant books, the only generally available choral settings of the Great O Antiphons were the settings for four-part choir (SATB) written by Healey Willan and published by Concordia Publishing House in the late 1950s. These settings have long been out of print. With the appearance of Lutheran Book of Worship in 1978 and Lutheran Worship in 1982, these great texts now have an official place in the Advent Propers for Evening Prayer. They are given in both LBW and LW in new translations common to all Lutherans in North America."

The doc goes on to promote the publication in 1985 by Concordia of the Willan antiphons in a new version edited by Carl Schalk and "carefully adapted to the new translations appearing in both LBW [Lutheran Book of Worship] and LW [Lutheran Worship]."

From their tattered condition, the copies used by the choir I used to sing with were certainly from the original publication.
