Lots of different versions of "Crazy", clearly, but the only one
that registers for me is Patsy Cline's.  (Britney Spears -- ugh!)

There is another YouTube video that does play Patsy's "Crazy"
(horribly out of tune) but the one that was first mentioned on
MMD struck me immediately as "O, Death", regardless of statements
otherwise; I guess that Gnarls just wrote a similar tune. :-)
