James Corden, Jane Krakowski, and Josh Gad stop traffic with one final street musical

We've had the last ever Carpool Karaoke, and now it's time for the final Crosswalk the Musical.

Marking the final week of The Late Late Show, James Corden joins forces with Jane Krakowski and Crosswalk veteran Josh Gad for one last medley of musical numbers in the middle of a busy LA street, from "Singing in the Rain" to "There's No Business Like Show Business".

The whole story may end in sudden tragedy, but it's still a cheerful watch.
