As far as those final two lines ...."It is the one thing in life where feeling better is pretty much guaranteed. Even if you walked into rehearsal exhausted and depressed, by the end of the night you’ll walk out high as a kite on endorphins and good will" .....I have experienced rehearsal nights where I did, indeed, walk out exhausted and depressed.
How about this article blog comment?: "Singing in a barbershop quartet, making those tight chords ring with such clear strong overtones, is really the most fun four guys can have with their clothes on."
Though the details about endorphins and such may be news, the psychological and spiritual benefits of singing shouldn't come as a surprise to any of us. Singing, like music itself, has almost magical effects on us. God seems to have made us this way. I read some years ago about a monastery in France in which the monks, after the musical change of scenery after Vatican II, became depressed and generally were not being their usual monkly loving selves. A psychiatrist was called in to assess the situation and he determined that the absence of the daily cycle of chant was the culprit. Chanting was restored, as was the monks' mental state.
