At the very beginning this was the original version of this song. So it is not an improvisation and the lyrics are "right". Only afterwards Robert decided to change the lyrics to what we know as "The Forest".
was this supposed to be the original A Forest, but they changed the lyrics then? Oh and on their Seventeen Seconds record there's the song 'At Night', but it has nothing to do with that, hasn't it? Or is this just an improvisation of A Forest and the (normal) lyrics were existent there, but they just changed it for fun?
