Series charting the history of the best of British comedy looks at Sorry!, the sitcom which ran from 1981-1988 and starred Ronnie Corbett as a middle-aged librarian who still lived at home with his domineering mother.

Corbett's character, Timothy Lumsden, not only tickled the nation's funny bones but also went on to influence a generation of younger comedians, such as Frank Skinner and Harry Hill. The writing team of Ian Davidson and Peter Vincent - who had also written for The Two Ronnies and Dave Allen - were adept at mixing comedy and drama, something few sitcoms were so successful at.

Comedy Connections reveals how Ronnie Corbett sought the opinion of comedy partner Ronnie Barker before committing to the project, how the writers knew they could take advantage of their star's diminutive size, quite how often Mother used to slap Timothy and that Timothy had a happy ending because the show's producer insisted on it before the start of the final series.
