Getting back to the clowning.....
Some of this stuff is pretty old, as for instance the the first tape which was recorded almost a decade ago. Clown masses seem to be one of those generational fads, as there was an outbreak of these back around 1970, and then everyone got it out of their systems and it became one of those things that people referred to nostalgically, ruefully, or as a present menace depending upon their theological politics.
The second clip is actually of an Episcopal service, specifically one performed (if you'll pardon the pun) at Trinity Wall Street back in 2005. (You can tell it's Episcopal because of the high production values.) Again, this was another one-off thing, and all the white-haired liberals waxed nostalgic about their hippy years, all the conservative radicals decried it as indicating that the church was a total loss, and everyone else (the vast majority) rolled their eyes.
Stunt masses might be considered an abuse, but really for the most part the remain freaks, and as long as one is warned and can avoid them, they aren't that imminent a threat. There is something of a tendency to engage in stunts at big ceremonial occasions, and that needs to be quashed; but that's where you have to rely on the bishop. (And while the chaos I've tended to experience in Orthodox hierarchical liturgies is not as bad, it's only not as bad.) The thing that is really soul-killing is the routine slovenliness, the weekly irreverence, the fear of doing things the normal way.
