First, this is not a spoof. Secondly, yes, most or all of the members were Catholic; one went on to become a Paulist priest. Third, I'm not saying that all Catholic pop rock from the early '80s was, um, well, uh...corny, strange, embarrassing, etc.. I'm just waiting for evidence to the contrary.
Yes, it's easy to criticize, especially when it comes to pop music from the late '70s and early '80s. But...ah, never mind. We now return to our regular Friday night lineup of meaningful, serious posts.
