James Corden and Josh Gad clogged up London traffic with some crosswalk musical renditions

James Corden added a new new entry in his "Crosswalk the Musical" series. This time, he booked the wildly accomplished composer Andrew Lloyd Webber who’s penned hit musicals like "Cats," "Evita," "The Phantom of the Opera," and many more. Corden, along with Broadway vet Josh Gad, performed impromptu versions of Webber's hits in the heat of London traffic - while amused drivers at red lights looked on.
