The last verse of this song goes:

See now the clouds flying over the moorland
See how the graves to the valley sides cling
Look at the mills now they're idle and empty
This is the valley where cotton WAS king

Many of the mills now have been demolished, some have been refurbished into heritage centres that tell us how things used to be or arty crafty centres that sell candles that nobody lights and teacloths that get hung on walls and never dry a pot.

A great song - I've been doing it for years and it's still part of the repertoire.
Cheers
