In September 1971, Christians from all over the UK held the Nationwide Festival of Light to protest against what they saw, as increasingly liberal attitudes to sex and the change in traditional family values.

Katie Edwards hears from three people who attended the event - organiser Peter Hill, Christian activist Celia Bowring and LGBT rights campaigner Peter Tatchell who protested against the event.
