Crosswalk: the Practically Perfect Musical

Let's head back out to the street for another "Crosswalk: The Musical" from The Late Show with James Corden.  This time, though, the street is a bit different -- not in Hollywood, outside of Television City, where drivers aren't bewildered by an outlandish theatrical performance popping up in front of them, but on the other side of the road in London  where...well, they sort of are.  And "popping up" is an appropriate term, as is the choice of musicals because it's their street production of Mary Poppins.  And to make things even more supercalifragilistic, the production has added a special co-star, Sir Ben Kingsley as 'Bert.'
