SilverEdge Systems Software hired Catherine Conrad to perform a singing telegram. SilverEdge arranged for James Bendewald to record Conrad’s performance of her copyrighted song to post on its Web site. Conrad agreed to wear a microphone to assist in the recording, told Bendewald what to film, and asked for an additional fee only if SilverEdge used the video for a commercial purpose. Later, the company chose to post a video of a different performer’s singing telegram instead. Conrad filed a suit in a federal district court against SilverEdge and Bendewald for copyright infringement. Are the defendants liable? Explain.
