I saw the (then untitled) Jake documentary a few weeks ago at its premiere in San Francisco. It's definitely worth seeing, and it will apparently be shown on PBS later this year. The SF screening was an event -- Jake was there and played some solo stuff (including Bohemian Rhapsody), a duet with his brother, Bruce, and a song with Bruce and their mom. In addition, Dominator played a song as the winner of a contest held in connection with the premiere.
