Yes, well said. But how much has anything really changed was the question. The original song is in the DT but as John Tams wrote a decade ago in the new chorus to go with MacColl's words:

Nothing changes, It all stays the same,
They're selling the moorland for profit and gain.
They've sold all the rivers, bought all the rain,
And you can't go up there, you're disturbing the game...

Cod's roe, caviar, milk stout and champagne,
Gold cards and dole cards, but, never the twain,
That's the game, that's their game
Nothing changes, it all stays the same.

(Recorded by Patterson Jordan Dipper on Flat Earth 2002)

How much does music change anything?
