Both films are great. The first concentrates on the Wordsworths, the second on Coleridge. A third, that didn't go ahead, would have been on Southey.
They are not by the BBC, who have issued a lot of Ken's stuff, but ITV the independent channel that Mevyn Bragg worked for. This may make it less likely it will come on DVD. I will update the site with more photos and details of both in the next few weeks, maybe that will compensate- I have copies of each but I am not allowed to copy on pain of death.
