I am curious, Martin Gibson, why you find it necessary to insult people--it doesn't seem to me that you really want this discussion to take place--curious to why that is--

Also, in the larger sense, why is the world's largest bookstore entitled to engage musicians but not pay them? I isn't a charitable event, in fact, it is a promotional effort intended to increase revenues for the store--musicians, like other skilled tradespersons, ought to be paid--People would be outraged if they tried to get masons to lay tile for free, or glazers to put in those big glass windows for free--if they demanded electricians to rewire those annoying fluorescent fixtures for free, they would be enormous outrage--

Don't tell me that it is the exposure--how much is that exposure worth when the main opportunity is playing for them?
