Oh man! Better catch Banksy's on the streets while you can!
Banksy's 'Occupy - The Musical' is gone and it has been buffed already! (click the jump to compare before and after pictures)
These 'The Musical' pieces were painted by Banksy 3 days ago, fueling the speculation that his pieces have already been painted around the city and are just waiting to be 'unveiled'. (i.e. claimed on Banksy's website and then defaced).
Also, there is no audio for 'The Musical' series, as of yet.
