Anyone see the 1/2 hour TV documentary last week on artists who have covered Leonard Cohen's work? I enjoyed it - any footage of the man himself is a rare treat.

I remember seeing and enjoying a film called 'Bird on a Wire' in 1976/7, which covered some LC live concerts. I've struggled in vain to get a copy of it - anyone know a source of this (or any other) LC material on video/DVD?
