The 80,000 seated London 2012 Olympic Stadium was packed with a dazzling extravaganza of music and dance that rocked.  The three-hour closing show starred the latest names in pop, a holograph of late Queen frontman Freddie Mercury, the Spice Girls, and Monty Python actor Eric Idle.  The Stadium was transformed into a mini-London, with model landmarks, including Tower Bridge and St Paul's Cathedral on a Union Jack shaped stage.
