Thanks David.

Yes, the line about the boy who drowned could be a problem. It's an allusion to the little Syrian refugee whose photograph went all round the world - kind of a stark contrast to the wealth sucked up by the Kim Kardashians of the world in the previous line. However, I must admit, not all that many folks are going to get the allusion and in a year or so, nobody at all will. I should probably ditch that one.

Good suggestion about where the song could wind down. The idea was to go from silly to slightly darker, but then I drifted off to the silliest line of all about all the people singing na na na na. The whole thing is a bit chaotic.

I've had some good feedback here. Thanks to all who have chimed in.
