Broadway musicals can have a bumpy transatlantic crossing. For every New York entry that repeats its acclaim on the West End, others quickly fade, while still others never make it to the capital at all: consider The Light in the Piazza, which won six Tonys in 2005 but hasn't yet been seen in the UK south of Leicester. What, then, of Shrek, DreamWorks's entry into the Broadway musical sweepstakes that called it quits in New York after little more than a year? It's way too early to tell whether London will prove the show's salvation, but at least it boasts two Nigels who between them are not to be missed.
