What's in a Name?

There are 14 guys in my a cappella group. Six of us have last names that start with S. Nine of us have last names that start with letters S-Z. Two of us have last names that start with B and the remaining 12 of us have last names that start with letters K-Z. The proximity of letters and high volume of letters later in the alphabet is somewhat strange and kind of an inside joke among us in the group. On the surface, this would seem simply coincidental. However, after reading the Segal article, I can't help but wonder if there is some connection. The article explained that cops in the academy listed friends as people with similarly alphabetically placed last names, which made sense because the roommates were paired alphabetically. They were exposed mostly to each other and became friends and could develop similar interests. All throughout schooling, I know that I was paired in groups, put on gym teams, and even sorted into homerooms based on where my last name falls alphabetically. I would generally be one of the later people in roll calls and making choices because my last name starts with Sw. I can't help but wonder if maybe somewhere along the way, we singers experienced some kind of alphabetical segregation that led us to musical interest. Perhaps we all had friends with similarly late-falling last names whose musical interests rubbed off on us.
