The case I make isn't a narrow one; you can widen it to any example where cash changes hands. This is not simply a case of an artist having a bad day. Davey's fans are entitled to expect value for money, just as you would expect value for money from any number of goods or service providers. You would not accept a poor job from someone on the basis of him being 70 years old, or was brilliant at his job when he was 28. You would not accept a poor job from someone on the basis that he happened to be drunk when he did a job for you, or hadn't prepared the groundwork necessary to carry out the job effectively. You would complain, and rightly so, and may take steps to get your money refunded.

There's evidence that these performances are well below an acceptable standard on an on-going basis - so good money will continue to be paid by unsuspecting fans until the wheels fall off the bandwagon. He should retire, or make serious effort to get his act together.

I have bought, and continue to buy his music - and will do as long as the product is up to standard; after that, I'll spend my CD budget cash elsewhere.
