Christians are dorks

This is a cringeworthy television advertisement from 1989, produced by the Christian Television Association. I remember them well from commercial television from the 1970s and 1980s. I conducted a not quite exhaustive straw poll of my Christian friends who are old enough to remember them. Just I as anticipated, none of those who responded liked them. I cannot find any information about this Barbershop Quartet group, if they recorded any albums or did any live concerts, touring the church hall circuit.
