Lyric discussion by KMP 

It's borrowing from 'Jerusalem' by William Blake.

'And did those feet in ancient time Walk upon England's mountains green? And was the holy Lamb of God On England's pleasant pastures seen?

And did the Countenance Divine Shine forth upon our clouded hills? And was Jerusalem builded here Among these dark Satanic Mills?'

etc.

The first two lines of the song are a present-day interpretation of Blake's - both question society [Blake critcises the industrial revolution of the 18th century, Ashcroft on globalisation/capitalism/mass-production].
