<p>Soozievt: you are so right about the wonderful a capella groups at Brown. Our favorite thing to do on Parents' Weekend was to go to the "Brown Derbies" concert, which also usually featured another group as well. Their CDs are fantastic...my son's high school friends all became fans through him due to his visits to see his sister. Harvard also has some terrific groups, but according to my son, none of them rival the Derbies!</p>
