For the record, I don't try to get everyone going, it just kind of happens sometimes
I have seen similar things myself this past summer where Joe KJ is setup at a fair or festival and allowing people to record their live performance for a fee. Usually it was between $3 and $10. At one fair it was free to sing but he charged to record. Most people paid for the CD
I think the key for the average KJ to stay in business profitably is to make changes. Whether that is finding new venues for their services or entirely new business models, there is too much competition for KJ's in the bars.
