At first I thought this might be a 'trick question', because it is almost word-for-word the title of a famous American jazz song. Anyway, here are a few of the lyrics:
~Do you know what it means to miss New Orleans
~I miss it both night and day
~I know that it's wrong ... this feeling's gettin' stronger
~The longer, I stay away.
...
~Do you know what it means to miss New Orleans
~And that's where I left my heart
~And there's something more ... I miss the one I care for
~More than I miss New Orleans!
Just a little cultural background info. Google the title ... or, if necessary ... BAIDU the title and you may even find an mp3 sample.
