When I attended, there was a lady that sang very loud and very badly.
We're talking, never in tune, with long, over-held notes that had a 'vibrato' that sounded like an injured animal, sometimes rising uncontrollably in pitch.
Imagine the worst singing you've ever heard, but worse.
It started to get out of hand when half the congregation was trying not to laugh during the songs. I can clearly remember opening or closing a meeting and ABSOLUTELY not making eye contact with certain ones when she was there ( which was always ).
Once you started laughing, you'd run the risk of laughing out loud during your own public prayer, which was soon to follow...
Don't miss any of it.
