The theme song used throughout the televised games was originally written as the theme song for The Adventures of Briscoe County, Jr.
Approximately 4,700 Olympic and Paralympic medals were produced by the Royal Mint at Llantrisant. They were designed by David Watkins (Olympics) and Lin Cheung (Paralympics). 99% of the gold, silver and copper was donated by Rio Tinto from a mine in Salt Lake County, Utah in the U.S. The remaining 1% came from a Mongolian mine. Each medal weighs 375-400 g (13.2-14.1 oz), has a diameter of 85 mm (3.3 in) and is 7 mm (0.28 in) thick, with the sport and discipline engraved on the rim. The obverse, as is traditional, features Nike, the Greek goddess of victory, stepping from the Panathinaiko Stadium that hosted the first modern Olympic Games in 1896, with Parthenon in the background; the reverse features the Games logo, the River Thames and a series of lines representing "the energy of athletes and a sense of pulling together". The medals were transferred to the Tower of London vaults on 2 July 2012 for storage.
The Olympics torch relay ran from 19 May to 27 July 2012, before the Games. Plans for the relay were developed in 2010-2011, with the torch-bearer selection process announced on 18 May 2011. On 18 May 2012 the Olympic flame arrived at RNAS Culdrose in Cornwall from Greece on flight BA2012, operated by a British Airways Airbus A319 named "Firefly". On the flight the flame was carried inside 4 miners lamps supplied by Protector Lamp of Eccles, Greater Manchester. The relay lasted 70 days, with 66 evening celebrations and six island visits, and involved some 8,000 people carrying the torch about 8,000 mi (12,875 km), starting from Land's End in Cornwall. The torch had three days outside the United Kingdom when it visited the Isle of Man on 2 June, Dublin in Ireland, on 6 June, and both Guernsey and Jersey on 15 July.
The logo stirred controversy as it resembles Lisa Simpson performing oral sex on Bart.
The value of the materials in the gold medal is about £410 (US $644), the silver about £210 (US $330), and the bronze about £3 (US $4.71) as of 30 July 2012.
