Helicopter Quartet

I saw a bit of a programme last night about Stockhausen's Helicopter String Quartet which involves each member of the quartet flying around in a different helicopter while playing lots of tremolo and yelling numbers in German. This is clearly where 4forte have been going wrong. Luckily they include the first page of the score on that webpage, so all I need to do now is turn up next week with four helicopters (and lose my fear of flying - although it may be overridden by my fear of Stockhausen...)
