Eurofest '75 was an International Youth Conference and Evangelistic Campaign organised by the Billy Graham Organisation in Brussels, Belgium. It followed on from Spree '73 held in London. The General Secretary for both was Harvey Thomas. Graham preached from Phillipians teaching on the connections between joy and prayer - two of the book's major themes. He insisted: "Young people should learn to pray." The festival took place from 24 July - 2 August 1975, in the Centenary Palace Exhibition Halls whilst the public Campaigns were in the near-by Heysel Stadium, Brussels.
