Four extra shows have been announced for John Water's critically acclaimed production Looking Through A Glass Onion - a homage to the music, mystery and memory of John Lennon – which will be performed for the first time at the Sydney Opera House from 30 November, 2010

Due to high demand, the extra shows will go on sale Monday 15 November, with the season extended to Sunday December 12.

John Lennon would have been 70 years old on October 9 this year and December 8th marks 30 years since he was tragically gunned down outside his New York City apartment, so the musical spectacle has special relevance for those who have celebrated Lennon's music in their lifetime.
