The excellent Ken Bowser documentary Phil Ochs: There But For Fortune is scheduled to be shown as a part of the "American Masters" series on Monday 23rd January.
Times vary, according to location, but tend to be in the late evening. Check your local PBS schedules for full details.
The American Masters series has long proved popular with PBS viewers, and will bring Phil's life and music to a much wider audience than at present. Recent years have seen something of a mini-renaissance on Phil's contribution to popular culture, and the 1960s in particular.
It's somewhat ironic that getting Phil and his music on mainstream TV is easier today, during a rise in ultra-conservative thinking, than it ever was during his lifetime.
