` ::::Key word there is ``can`` only if you are making it up as you go along.  And it has nothing to do with ``parochialism``.  There are strict rules that govern the British honours system which are recognised by most governments - including the Irish Republic.  ``KBE`` is a formal state award and a proper, diplomatically- and internationally-recognised ``post-nominal`` and so (formally at least) should appear after one's name/title.  I don't believe awards such as a Grammy are considered post-nominals and formal state awards...... (Interestingly, and as a related side  note, if one has a knighthood one is banned from using nicknames with the title: for instance it is ``Jimmy Goldsmith`` or ``Sir James Goldsmith`` but categorically not ``Sir Jimmy Goldsmith``.)  `
