To jazz up Classical music or not?

I knew a violinist in college who didn't care for watered down versions of Classical pieces.  She was not a "Hooked On Classics" fan and thought Classical pieces should be played as they were intended.  It's a given, then, that she wouldn't have liked Walter Murphy's "A Fifth Of Beethoven."  I wonder what she thinks of Pink Martini's "Bolero," though.  Even the most militant Classical purist ought to appreciate the group's reverence for Ravel's masterpiece.
