Between Two Worlds: A Journey to Calcutta This year, 1985, is the International Year of Youth. The oldest youth organisation in the world - the YMCA - is contributing to it with a special project: taking 20 young people from Britain to India, to work with the destitute of Calcutta. They will also help out on rural development schemes, aimed at stopping thousands more joining the three million who already live in the city's slums.
Some of the youngsters making the journey are unemployed, one is a striking miner. Each of them has had to raise F700 to go with the group.
Everyman travels with them -from one world to another.
