Was that the block that used to show Who, Blake's 7 and The Prisoner (plus something else; I forget what), all in a block on Saturdays? That was a loooong time ago, but I LOVED all of those shows dearly. It was one of the few things that made the move to Houston in my teen years bearable.
When I was in high school, I even got to go to a Doctor Who convention at the Shamrock Hotel, right before they tore it down. Colin Baker was there and he showed one episode they'd just aired. It was the first one of his that I got to see--"The Twin Dilemma."
Fuck, I'm old.
