In 1970, Ray Foulk and his brothers staged the third Isle of Wight Festival 1970 which was the largest such event in British history and is believed to remain so to the present day. Although figures vary, the "Guinness Book of Records" estimated 600,000, possibly 700,000 people attended. The raft of world-class artists appearing included Jimi Hendrix, Joan Baez, Miles Davis, Leonard Cohen, Joni Mitchell, Emerson, Lake &amp; Palmer, the Who, the Doors, Kris Kristofferson, Chicago, Jethro Tull, Ten Years After, the Moody Blues, Free, John Sebastian, Donovan, Melanie, Sly and the Family Stone, Procol Harum and Richie Havens. The festival created a furore among hostile Isle of Wight politicians and resulted in a parliamentary bill to curtail further large-scale overnight gatherings on the Isle of Wight. In 1971, the act passed into law, curtailing all such future festivals.
