Recorded on location, the programmes follow the routines and rituals of individuals who have built them up over uears of dedication.
At the core of each programme Gerry engages with them on a one to one basis, testing out and exploring why they give so much time and creative energy, often to the exclusion of more normal aspects of daily life.
As an observer and commentator, he draws the viewer's attention to detail and idiosyncrasy that a casual glance might overlook.
To each new experience he brings his personal view and with a gentle style, never patronising or insulting, he wonders aloud what some of the subject's friends and relations have confided in private.
At the climax of each programme, Gerry joins in a major event that celebrates the collective enjoyment or passion of large numbers of like-minded people.
