For many years, Mike answered virtually all of the fan mail himself, usually with short quips on assorted postcards. Occasionally, mail addressed to others in the band would be answered individually by them. And a very small proportion of fan mail was answered in the newsletter (see, e.g., treatment of YEM lyrics).

At some point, the mail because either too plentiful (and/or repetitive) and the role was taken over by Betty Frost. Who is she? ... We don't know, other than the person who answers fan mail.

Cheshire Cat: That depends on where you want to get about any given issue."
