Allentown's embattled Crocodile Rock Café faces legal action from the music industry for allegedly violating artists' and publishers' copyrights by playing music without a license. The lawsuit in federal court claims the nightclub hosted live musical performances and played recorded music after its license from Broadcast Music Inc. expired in March 2011 and that efforts to get the owner and managers of the club to renew the license were unsuccessful. "It's true that if you have a little café that has a radio playing in the background, you're probably going to get a knock on the door," said David Post, a professor at Temple’s Beasley School of Law.
