Grocery Store Musical - Improv Everywhere Strikes Again

 I'm a BIG fan of Improv Everywhere!

"From pantless subway rides to invisible dogs, Improv Everywhere has orchestrated its fair share of stunts -- always bringing joy to the participating "agents" as well as the unaware public becoming an audience to the spontaneous scene. Founder Charlie Todd decided to create a musical flash mob in a random Queens, NY grocery market, asking composer and lyricist team Anthony King and Scott Brown (of 'Gutenberg! The Musical!') to create the perfect grocery store number."
