Ever been serenaded by a friend or loved one?  it's a pretty romantic thing to do.    back in Mozart's time a serenade didn't just involve 2 people, though-- serenades were party music used for celebrations and gatherings of any kind.  Mozart's Serenade #13 (A Little Night Music) just may be the most famous classical party music of all time!  hear it today on the Mozart Buffet, Noon to One, on 89.5 FM and kbaq.org.
