O magnum mysterium ... back about 1977.

I heard "O magnum mysterium" (Tomas Luis de Victoria, 1572) this morning on 90.5 FM, and it utterly floored me. Maybe it was the rain and the seasonal blahs, but what a sucker punch! Recollections of my bass part are fading after almost 35 years, but the many fond memories of high school choir came rushing back. Thanks yet again to Mick Neely for teaching me this music.
