When London Grammar came out onto the stage our first reaction was, but they are just kids!  They are so young.  Indeed they are young,  but they sound not only mature and unique but also simply amazing.  Small venue packed to capacity, no one getting drunk, no one smoking and no one pushing or shoving  to get a better spot. People came, got their beer, staked claim to a piece of the floor they were going to occupy and simply enjoyed.  It was so civilized.
