By the way, when did Mark write Rüdiger? Didn't he start it in the early 80s? IF that's the case, and IF the 96 version has any traces of the music when Mark first started working on it, to me it sounds like it could have been "conceived" during the LOG era. Would be awesome to hear it played on a Spanish guitar and with marimbas.
It was surely late 70s, because I remember there exists an early demo with David, and it is quite different musically compared to what we know from 1996 :-) Jeroen has it on his website - on some compilation bootleg if I remember correctly.
