Today was the feast of "St. Joseph the Worker" which was instituted in 1950.
The Gregorian chant for this feast is so modern and ugly, that even St. Thomas Aquinas Seminary used to "Psalm tone" the propers for this feast (when I was there, 2000 to 2003), even though this was otherwise NEVER done at the Seminary. Every Sung Mass was normally 100% full Gregorian chant propers -- even when this seriously lengthened the duration of Mass.
The only exception, when the seminarians used the abbreviated "Psalm tone" chant propers, was St. Joseph the Worker's day (May 1st). The professor in charge of Gregorian Chant at the seminary, Fr. Thierry Gaudray, even approved of this.
Isn't it interesting that such a feast is new enough to be criticized like this, but old enough to be used at many (most?) Traditional chapels?
I mean, it's a fact that the Communists hold May 1st to be an important feast day. And the Pope even emphasized how St. Joseph is the model and patron of workers (rather than the Communist party, which was always jockeying for this position!). It's obvious Pope Pius XII was trying (wisely or unwisely) to co-opt or steal the thunder of the Communists, who are traditionally demagogues trying to mobilize the "workers" to get what's theirs from the nasty capitalists.
I'll never forget some of the Canadian seminarians at S.T.A.S. used to tongue-in-cheek call this feast day, "St. Joseph the Red" (the "red" referring, of course, to communism). I thought it was quite witty.
