No worries, Thal, just bring that bike over here some time and I'll run a cross-pin into the saddle stem and frame for you - that'll fix it! (of course I'll take care to randomise the position before I do it).
I'm a great believer in sitting really, really low at the piano. I got to be that way not least out of comfort considerations, but I also feel I have better control by pulling the keys down rather than pushing, which obviously is more the way the lower one is. I do think that sitting very high leads to all sorts of strange and unnecessary postural contortions, but I wouldn't expect everyone to go to my lengths.
