The 2001 album Rock Action has a fair few tracks with vocals, not their usual style, and this one in particular doesn’t sound very Mogwai at all. It’s a lovely song with vocals in Welsh by Gruff and Cian from Super Furry Animals. I suppose the coming together of Scots and Welsh does give it a very celtic folky feel. I imagine it playing while I’m sat by the fire in an old pub with a pint of Brains Bitter on the go….or walking up the hill towards a wicker man….a weird combination of those two things.
