Really like it. Yes, it's at the top of MK's range but his whole vocal schtick is singing like he's fighting for control and I think the timbres of their voices work beautifully together.
As for Guy's comments on the mix - I can only assume he's never listened to any classic Van Morrison. It's mixed *exactly* like a 70s Van Morrison, presumably deliberately. I'll make him the allowance that he's too young to know better - except he's older than me!
