The food and the wine for the celebration were provided by the Parisian restaurant Maxim's.[8] 600 guests dined over five and a half hours, thus making for the longest and most lavish official banquet in modern history as recorded in successive editions of the Guinness Book of World Records. A son et lumière show, the Polytope of Persepolis designed by Iannis Xenakis and accompanied by the specially-commissioned electronic music piece Persepolis,[9] concluded the evening. The next day saw a huge military parade of armies of different Iranian empires covering two and half millennia by 1,724 men of the Iranian armed forces, all in period costume, followed by representatives of the Imperial Armed Forces, with a large military band, manned by military musicians and providing the music for the parade, split into two - the modern band playing in Western instruments and a traditional band wearing uniforms of the bandsmen from different eras of Iranian history.
