Carry on Loving (1970)

The Wedded Bliss computer dating agency aims to bring together the lonely hearts of Much-Snogging on-the-Green. Its owner, Sidney Bliss, has enough complications in his own love life, but still produces a pamphlet called "The Wit to Woo". The strange collection of hopefuls leads to some outlandish matches, and jealousies are bound to lead to trouble.
