Performing bands included The Byrds, T. Rex, Santana, Jefferson Airplane, and the headlining Pink Floyd. Approximately 100,000 attended. Festival posters show that the festival was billed in Dutch as 'Pop Paradijs' and 'Holland Pop Festival 70', and that the main investor was Coca-Cola. In both English and Dutch, the festival is also known by the English name "Stamping Ground", and is often billed as the European answer to Woodstock. It took place approximately one year after Woodstock, and two months before the third 1970 Isle of Wight Festival (the first two being held in 1968 and 1969).
