Cosby has been out of the comedy circuit after more than 50 women accused him of sexual misconduct. A 2004 incident went to court and after a jury couldn't reach a verdict last year, the case was set for a re-trial, which is coming up in April. The woman accused Cosby of drugging and raping her.。

After the show, he spoke to reporters at the club and said he had no comments about his upcoming trial. Instead he reflected on his first appearance in years outside of court. "This is life," he said. "And life changes. And so it's not to be feared to go out. I go out."。
