Here's a short instructional film about walking in case sitting on the sofa consuming ginger snaps and custard creams and fizzy pop like the world has ended has caused such a bizarre activity to slip from memory.
Unfortunately, despite the tunefulness, should one undertake anything shown in the video in Scotland (or Wales) you are very likely to be shot on sight, which is where the harps come in.

That video is faintly disturbing. They're far too happy...

I wasn't aware they made Stepford sisters.

Do you know I was thinking the same thing ?fishes?.  Or a scene from some of the truly disturbing ?black mirror? series. 

They do give me the same slightly uncomfortable feeling I get when I see automata in action.

Well watch this then, it'll take your mind off it. Nearly as good as the "badpiper" covering this song on bagpipes with fire shooting out. (Easy found by searching on You Tube.)

Angus Young eat your heart out.
