Anyone who enjoys the classic Doctor Who series will without a doubt enjoy "The one with the Maggots" as it is known. Features the departure of Katy Manning who portrayed Jo Grant from 1971-1973.The commentary is special as actress Katy Manning is delightful to listen to as she reflects back her moments with late Jon Pertwee. As she watches her departure scene, Katy breaksdown and cries as she realizes how much she misses Jon. That alone is worth the DVD. Its very touching.
