Van der Graaf Generator — Nutter Alert

It might come in a letter Darkness falls in a telephone call; I await the unexpected With one ear to the party wall Is it the pricking of the conscience Is it the itching of hair shirt Is it the dictionary definition Of a precipice to skirt? It's the nutter alert Though this face is familiar Something in it has bred contempt; I never asked for your opinion Or your back-handed compliments Oh, but here comes that special nonsense All the words out in a spurt The unhinging of the trolley As the mouth begins to blurt... It's the nutter alert I can see we're in trouble From that glint in the eye you've got; There's no sense to the story Comprehensively lost, the plot And how contorted is that logic You so forcefully exert: You're a car crash in the making Head-on, that's a racing cert It's the nutter alert This is the nutter alert
