There was a point around 'Assembly' / Nation 12, when I honestly believed I would never, ever get to see John live - so I never get bored at his gigs. There's usually at least one jaw-dropping moment that will remain burned in my memory long after the event is over (too many to mention now).
However my missus says that if he does another extended version of 'Burning Car' she will kill him!
Personally, John can whistle 'Burning Car' over and over again and I'd still pay to see it
Regarding projected images - I wonder if the reason he hasn't done it is because he wants to do it properly - being as he is an expert at it after all - and at present, doesn't have the means to do it his images justice in a live environment.
