The Erdős-Bacon-Sabbath Project

The Erdős-Bacon-Sabbath number combines three measures of professional collaboration to make a fun (if rather complicated) parlour game for the internet age. If you can find someone who has published academically, been involved in a movie or TV show, and publicly performed a song, they may have an EBS number. The question is, how many degrees of seperation does it take to connect them to mathematican Paul Erdős, actor Kevin Bacon, and rock band Black Sabbath?
