What follows is a list of the names of firms (groups of hooligans) gathered and given to us by two people who have assisted us with our research.  It is clear that many clubs have more than one named group, but the list is by no means complete because new outfits are being formed and developing all the time.
 It will nevertheless give some idea of the range if clubs which have firms attached to them and which may well be meeting some time in the near future.  For the record, Wigan Athletic, who have an average attendance for home games of about 2,000, recently took a firm of approximately 400 to Blackpool for a pre-arranged 'meeting'.  And you thought we were joking?
