<p>I saw a piece on TV about the huge a capella scene at Yale. There they have a tryout system that runs much like a frat/sorority rush. For several weeks, candidates audition for one or more groups that they are interested in joining. The groups take notes and hold meetings to rank the candidates and decide whom they really want.</p>
<p>At the designated time one night, the current members of the various singing groups assemble outside the closed main gates of the university. The candidates wait nervously in their dorm rooms. At the appointed hour the gates are thrown open and the kids run to their assigned candidates and put dibs on them by giving them official invitations to join. The fastest runners in each a capella group are assigned to dash to the rooms of best singers among the candidates - sort of an Oklahoma land rush. I thought the whole thing was kind of cute.</p>
