Actually, I'm onboard now, too.  What would be most relevant is simply ""years old""; the age of the universities here is rather irrelevant.  Perhaps a third column could include... whether they're all male?  their web pages? whether they have a cappella subsets?  Some other useful, column-worthy information that, through a group comparison, helps better grasp the nature of glee clubs.

I'm not really a huge expert here, but is there more information about the glee club as an organization before it became transplanted and took roots in the universities of the U.S.?"
