Horses for courses I suppose then? 
I think it's harder to tweak the colours back using sliders once its committed to jpeg. Any shots that I've taken even when there is a real orange sodium light have been rebalanced reasonably well with the RAW an for me that's anything that isn't blue or orange...I get the feeling that's what Ridg and Alistair were saying too.
Movement in the clouds was nice and I've still to achieve that. I never get out when it's windy enough
Essentially, the accepted rule of thumb is you balance for the key light which is the sodium street lights. Doing this would make the sky look unnatural though, so you would layer a copy of the image (balanced for the moon) and blend the two together.
No I don't mind at all, but that shot is nothing like how it actually looks. It really is that orange down there! That second shot looks really unnatural?
I disagree, it's a closer reflection of the scene to your eyes, but it's certainly not natural, how much orange grass do you get in stoke? Are orange leaved trees localised to the the canals too? The human eye at night is massively flawed and doesn't register colour properly at low light levels, fortunately the camera can perform better in these conditions. Granted the street lamps produce an orange glow, but if you balance for them then your colour reproduction is
wrong. As dTea said it's horses for courses but to me the wrong white balance adds nothing to the scene and is quite detrimental to the overall image.
