I have thought that some of Sir JOhn's posts in recent months have displayed a slight lasssitude, a tiredness of spirit. The youthful edge perhaps slightly blunted, a world-weariness descending and pinning down a spitit trying hard to fly as energies dissolve away. And then, suddenly, the post about accordions above: the genius is back! Sir JOhn's himself again! I feel rejuvenated, alive again. A classic. JOhn, I salute the undisputed master.
