When we lived in Sweden we saw a few episodes of “The Prisoner”. This was probably '71 or '72; we think our TV was taken in a burglary before Christmas 1972. One episode that stood out was when No. 6 listened to identical LPs and declared that one was too fast and another was too slow. I have been trying to remember what the piece was for years. I do know that I bought a copy of it later based on hearing it in “The Prisoner”.
I have been working through the DVDs from Netflix and finally watched the LP episode. It is the second episode on Vol. 7, “Hammer into Anvil”. But No. 6 doesn’t make comments on the speed in the shop, he just looks at his watch.
Another difference I remember is that in the opening of the BW version we saw, the guy in the top hat sticks a cane or an umbrella to knock out the soon-to-be No. 6. In the Netflix version, we only see the cloud of gas coming in the keyhole. The BW version had No. 6 caught in the big bubble; in the Netflix version we only see it coming out of the water and bouncing along the beach.
The LP? “L’Arlésienne” by Hector Berlioz.
From http://www.imdb.com/title/tt0679180/trivia I learned why “L’Arlésienne” was chosen. If you haven’t seen “Hammer into Anvil” yet, see it before you check this link.
