If you would like the specific names of all the episodes involved in any of the three series, you may contact me privately.
This last snail mail catalog doesn't list other shows that GT is in which they carry, but I assume that they still do. Other shows are Strangers and Brothers, Edward the King, and Peter and Paul. I bought Edward the King and Peter and Paul and enjoyed them immensely. I didn't buy Strangers and Brothers because I had decided to start trimming my tape collection by the time this was offered. Anthony Hopkins is in both Strangers and Brothers and Peter and Paul. Timothy West stars in Edward the King.
All videos from CC are NTSC VHS and all DVDs I assume would be for American DVD players.
