well I'm from the Philadelphia Archdiocese and I still see the "happy clappy" masses all the time. It still happens at St. Titus in East Norriton. They still have the guitar and drum masses every satruday night. To top it off, before giving the final blessing, Father Wetzel will ask all of those who have birthdays to stand up and sing happy birthday. That is why I attend the local Tridentine Indult.
The last 11 years worth of bishops of the St. Louis archdiocese are mentioned in this article and there are a number of this sort of Mass still happening around town. Separating the people from the "heritage" of being the birthplace of Jesuit folk music is proving difficult.
