O.K. Puzzle 150 is Satie's Sonatine Bureaucratique.
Quite right, Bryn. I thought it might have fooled people because it's Satie's take on a sonata by Clementi, one that is popular with beginners on the piano.
Oh, I seem to have missed your previous message, sorry.
Aha! I thought you had treated it with due contempt for its mock equivocation.
I introduced myself to Satie's muse via the old Frank Glaser LPs, back in the '60s, then got a much deeper education in the delights of his work from the advocacy of Chris Hobbs and Gavin Bryars in particular. I probably know the Satie sonatine better than the Clementi it 'pays tribute to'.
