lol i know it doesn't have to do w/theory...but it's music, so what the heck
While I was preaching in a church in Mississippi, the pastor announced that their prison choir would be singing the following evening. I wasn't aware there was a prison in the vicinity and I looked forward to hearing them.
The next evening, I was puzzled when members of the church approached the stage. Then the pastor introduced them.
"This is our prison choir," he said, "behind a few bars and always looking for the key."
