Wikipedia says that Edvard Grieg had Scottish roots, and the family name was actually Greig. I've often wondered whether Edvard might be related to folksong collector Gavin Greig (1856-1914), and Wikipedia confirms my suspicion.

As for André Previn, I think he made classical music much more approachable for us who were raised on Peter, Paul & Mary (and PP&M made Texas Gladden much more approachable for some of us, so it all works out in the end).
