I can't remember when I first heard this. Years ago. And still when it pops up on shuffle I get a grin on my face. The sound is so rhythmic and rich and joyous. And then, when you know the back story it gets deeper; Les and Mary laboriously laying one track on top of another, inventing a whole recording industry while making something poppy and irresistible that still sounds newly minted today. The chug of that guitar in the background is gorgeous, and there are the simultaneous swooping harmonies and the little jabs of solo. If music had just sounded like this forever that would have been fine.
I think it makes me happy in the same way Aardman animation does - light and lovely on the surface, yet you know, deep down, it's the product of a man in a shed - simultaneously contented and obsessed.
