Arch Oboler had nothing to do with "Quite Please"... The only association is that Oboler did take over one of Coopers earlier programs.
Years prior, Cooper created the show "Lights Out" which became popular, but after 3 years he left the show to go to Hollywood to write movies (he wrote Son of Frankenstein), anyway, when Cooper left, his "Lights Out" show was handed over to Oboler, who did very well with it for years to come, and then when Cooper came back to Chicago he started Quiet Please.
The big problem is that most of the episodes are very poor copies, but a few of them are crisp and clear. http://quietplease.96.lt
