I would love to have seen it.
And if the crowds are anything like the ones the Elephant attracted in London, then the amount of money per pleasure per person is actually quite small - and a little money per person spent on enjoying something together in a peace, creating wonder and imagination, is very well spent.
Typical that the rail network leading to Liverpool is in total dissaray - it takes 11 hours to get there fom London on some servoces...so revenue for tourista will be more limited...well mnaged as usual...
