In the YouTube interview clip I posted above Chip says they were in the possession of Jim Dickson, and were lost over the course of time. That's one vital missing link in the Gene chain that's never going to be known to us. However, I am hoping that there are some Clark demos still in existence, like 'If I Hang Around', from Byrds Parts 2, which I thought was fantastic. Up until that release, who even knew that tape existed? Joel is currently a member of the Emitt Rhodes Band, so you can be sure I'll ask about that.
