From 2 July 1968, Tom-Tom was hosted by former ATV London continuity announcer Norman Tozer, with Carrad remaining as part of the presentation team alongside John Earle and Janet Kelly.
The series continued through 1970, with features including a film-making competition (Tozer would later write two books aimed at amateur photographers and film makers).
