Patrick Swayze wrapped up shooting for his TV show The Beast today after celebrating at a Chicago club. The cancer-stricken actor showed up at Underground last night with his wife, looking "relaxed, laughing easily," an eyewitness told Us. Scruffy-faced and casual in a hood and cap, he didn't circulate or stand but chatted as fans dropped by. He "didn't appear drained by the appearance at the event," the source said.
