39 Steps lively

The 39 Steps, which opened at the Roundabout's American Airlines, and is now at the Cort, will relocate to the Helen Hayes come January. I enjoy when Broadway shows roam all over town, which was commonplace in a bygone era but happens infrequently today. (I think the last was Chicago, but its multiple transfers have occurred over 12 years; The 39 Steps opened in January.) By all means go see it, but check first if it's on the move.
