At this point, Wicked is almost as famous as The Wizard of Oz.
'The Untold Story of the Witches of Oz' follows Elpheba (later known as 'the wicked witch') and the good witch Glinda long before Dorothy dropped in.
It's one of the most successful West End shows ever, and has played to over 8 million Londoners.
If you're turning green with envy, there's good news: it's currently on tour. The musical will be playing theatres around the UK until next January.
