An International Youth Conference and evangelistic crusade organised by the Billy Graham Organisation in Brussels, Belgium. It followed on from Spree '73 held in London. The General Secretary was Harvey Thomas.
Many well-known evangelical figures first came to prominence at it, such as Luis Palau, Bishop Festo Kivengere, Annie Vallotton the Good News Bible illustrator and Manfred Siebald the German singer-songwriter. One of the special guests was Cliff Richard.
The festival took place from 25 July - 2 August 1975, in the Heysel Stadium, Brussels.
Billy Graham preached from Phillipians and taught on the connection between one of the books themes - joy, and prayer.
Billy Graham said, "young people should learn to pray."
The Finish group Treklangen sang the theme song: "I don't know what you came to do, but I came to praise the Lord". They recorded on the Pilot label in English and Swedish as well as their own language.
