Yet another of the big musicals has posted its Broadway closing notice: Young Frankenstein will shutter on January 4, 2009. Like the soon-to-be-closing Hairspray and Spamalot, Young Frankenstein is one of those shows popular with tourists looking for a big, splashy Broadway musical. But unlike Wicked and Jersey Boys, these shows have long had middling ticket sales, meaning that the current economic woes are just too much for them to survive on Broadway. The much newer musical, 13, is also ending its run on January 4. With the cold, quiet winter months ahead, many Broadway producers have decided to pack it in right after the popular Christmas holiday, knowing that ticket sales will dip considerably in the New Year.
