At about 43 minutes in, Barnaby and Jones are walking on the concert property. Jones has a t-shirt. It then cuts to another shot of them walking a little further over, and Jones is now wearing a coat over his t-shirt. He had not been carrying a coat.
Both the "Axeman" and DCI Barnaby refer to the electric charge being activated by the "Axeman's" Wah-Wah pedal. When they show the pedal it is a standard effects pedal, not a Wah-Wah which has a distinctively different shape. It is possible the pedal is an "Auto-Wah" but no old time blues player would ever use one, preferring the standard "Wah.
Mistook Left Brain behavior for Right Brain
Barnaby says with deep conviction, after checking suspicious electric outlets:
"It's all very premeditated isn't it? Musicians function in a more left-brain, impulsive manner. This is a right-brain MO. Somebody has thought this through very, very carefully."
It is the Left-brain that is linear and methodical, and the right-brain that is creative and creates its own reality, not as Barnaby states.
