BKLYN — The Musical gives itself a headache for no reason. What does ‘BKLYN’ mean? Perhaps it’s a random jumble of letters caused by a muffin landing on the keyboard. A punter who sees the title once and later looks it up online is unlikely to recall the precise order of the letters, and his search will probably fail. And he’ll have trouble discussing the show with his friends because he won’t know how ‘BKLYN’ is pronounced. It turns out that the show’s heroine is called Brooklyn, and the writers decided to capitalise her name and extract three of its letters. Sensible theatre-makers don’t create problems like this for themselves.
