I think Philadelphia was one of the dioceses that somehow remained relatively traditional after the council, at least till the end of the 80’s when things fell apart. Fiddle backs, decently vested altars,lace, even communion at the rail were still common throughout the city for a long while.

Part of that was the late Cardinal Krol, who, though I have nothing positive to say of him as a person or archbishop, he did keep things strictly in rein. It was because of him that that cathedral never had it’s altar rail removed, and that the original high altar continued in use up until the days of the current archbishop (who, sadly, has discontinued that and ordered a roll-away table be put in the choir, with much opposition from the cathedral rector and the office of worship.)
