On Saturday, Feb 28, 2009, he performed the Opry with his father-in-law Charlie Haden. The pair were joined by bluegrass stars Sam Bush, Bryan Sutton, Jim Mills, Andy Hall, and Stuart Duncan. Haden, of course, played bass. Jack Black sang and, in part, acted out, the traditional tune Old Joe Clark. Here’s a fan recorded youtube video.
Be sure to check out the photo, while he was there, Black took the opportunity to get his photo taken with Del and Ronnie McCoury and Sam Bush.
