Howard Crabtree’s When Pigs Fly, which was recently advertised as being in its last weeks, will roost at the Douglas Fairbanks Theatre at least through August. Press rep Tony Origlio said sales for the long running Off-Broadway revue had picked up in recent days. The extension will allow Pigs, which opened on Aug. 14, 1996, to reach the two year mark. The show yet features three of the original cast members: Stanley Bojarski, David Pevsner, and Michael West. Origlio said the cast would most likely remain intact throughout the summer.
