@DJDarren #ThePlaylistSuggestion
Curtis Mayfield - (Don't Worry) If There's a Hell Below, We're All Going to Go
(there's a three-and-a-half minute version of this, and there's an eight minute version. Choose wisely.)

Frankie Archer - Close the Coalhouse Door
(because it's about mining. There are many versions of this song, but Frankie Archer's take was one I found by chance, I'd never heard of her before and it blew me away. Now a huge fan. She's great.)

Mercury Rev - Holes
(holes, as it says, dug by little moles - so they must be underground tunnels)

The Unthanks - The Testimony of Patience Kershaw
(again, it's a song about mining.)


Bed suggestion:
Black Dyke Band - Gresford (The Miners' Hymn)

I could suggest lots of songs about mining, but I'd better stop there.
