his voice is almost gloomy, but in a striking and haunting way. it does fit the mood of the song--it sounds earnest and intense without being too singer-songwriter-y.
one of my favourite pink dots song. i suppose because, for me, they always manage to convey a sort of 'it's the end of the world' vibe. and the lyrics are cryptic enough that you can't always tell if the presumed outcome is hopeful or not.
