"In 1973, the government of France banned the Rolling Stones from entering French territory because of various run-ins with the law—most of them occurring during summer of 1971, while the band members were in the South of France, recording one of their masterpieces, Exile on Main St. This was a blow to the Stones’ hordes of French fans, who would be shut out from experiencing the Greatest Rock ‘n’ Roll Band In The World on their 1973 European Tour in support of the newly released Goats Head Soup. That October, the band organized a concert across the Belgian border in Brussels, and a local radio station chartered a bus to transport French fans to the now-historic gig."
