 last decade there was a web site for the RMT that was run by a person as friendly as the folks here. He had to "retire" from it given his own work. That website, too, had "Show of the week". I think 2-3 times they "double dipped" on the SOTW when there were two episodes that were worth comparing. I can remember three (maybe the only three);

1. "The Laughing Maiden"/"Yesterday's Giant" (for the reasons above)
2. "Time and again"/"The Vampire Plant" (for the reasons above minus Norman Rose plus Ian Martin as a secondary player; both were excellent Ian Martin plays that were very similar vampire stories using very unconventional "vampires"), and;
3. "The Memory Killers"/"The Ghosts of Yesterday": Both of these dealt with survivors of Nazi atrocities, and were fascinating in that: A) the first was written by the wonderful Sam Dann, the second by his daughter Victoria, and; B) the first dealt with an American bomber crew member (Ralph Bell) who spent time in a stalag, the second an American upper middle class housewife (played by Teri Keane) who as a child survived an entire village massacre by the WWII Germans, with each confronting someone who gave them immense pain in the past.

Not trying to give "information overload" here (don't think I ever could to an RMT listener). Just remembering the special distinction we gave these plays "back then".
