When you've played it a few times you quickly get over its meretricious side (provided by that ghastly C natural, but, as a diatonic harmonica player, I would say that, wouldn't I?) and come to heartily dislike the tedious thing. Ungar's version is sleep-inducing, but some of the versions I've heard on Classic FM down the years are positively buttock- clenching. The word "stasis" springs to mind for some peculiar reason.
