thats better. I couldn't mention the Red Queen while I was a polite guest.
So how do you define pop music?
Is it music published by the aforementioned industry (which certainly goes back as far as Playford)?
Is it music played by that thing in the corner that you put money into, that in my day was called a Wurlitzer, but I believe it used to be called a minstrel, or bard, or Joe the pianist, or sometimes 'the geezer with a squeezer'?
Or is it music enjoyed by uneducated people, like that collected by Mr Sharp?
