Educating Archie - Ugh!
For a 10 year old, plus or minus a bit, why??
Granted it featured the worlds greatest radio ventriloquist, but the artists who also got air time include Benny Hill, Julie Andrews, Max Bygreaves, Beryl Reid, Bernard Bresslaw, Harry Seacombe, Hattie Jaques and probably many others (not to be confused with Manny Others, a session saxophonist). OK the scripts were naff, but rationing was still going on and times were hard, even if we didn't know it.
Journey into Space - the program that you listened to from the safety of behind the sofa. And "The Day of the Triffids", which required you to be even further behind the sofa. Especially when that Whitacker was about.
Fairly sure the "memorable piece from Take it from here was "Ohhhhh Ron" and was Joy Nichols to Dick Bentley, Jimmy Edwards being Pa Glum.
In many ways, radio had a lot over TV, as long as you were able to supply the pictures in your head. The scenery was cheaper, as well. Something like Hordes of the Things" would probably bust most budgets.
