Here's a look at some BBC TV and Radio highlights from Thursday September 5, 1974...
Mastermind began its 3rd television series on BBC1 on September 5, 1974.
Presented by Magnus Magnusson the programme immediately followed Top Of The Pops and was a cut above most quiz shows with contestants selecting a diverse range of specialist subjects. As those taking part were usually schoolteachers or lecturers, the series served to educate as well as stimulate.
Mastermind still continues in 2013 now presented by John Humphries.
The first series of Dick Clement and Ian La Frenais prison based sit-com Porridge followed at 8.30pm. Ronnie Barker played the part of lag Norman Stanley Fletcher serving a five year stretch at Her Majesty's pleasure.
The series originally evolved from a half hour pilot starring Barker in 1973 entitled Prisoner and Escort. Fulton MacKay and Brian Wilde resumed their roles as Mr McKay and Mr Barrowclough from the pilot, while star of The Lovers Richard Beckinsale took on the role of first-time offender Lennie Godber.
Porridge ran for three series until 1977. A sequel entitled Going Straight was later made as well as a full length Porridge movie in 1979.
Over on BBC2 at 9.25pm Ronnie Barker returned as a special guest of singer Lulu along with Adrienne Posta in Show Of The Week.
Show of The Week had been on a popular fixture on BBC2 since the 1960s encompassing a variety of shows hosted by entertainers including Morecambe and Wise and Vera Lynn.
Lulu herself had been hosting programmes on the BBC since the 60s and was seen as a seasoned professional all-round entertainer by 1974 despite still only been 26!
If you were winding down with the Radio 2 after 10pm Bob Holness was presenting Late Night Extra. Tonight's special guest was Jessie Matthews OBE.
A star of stage and screen in the 30s and 40s, Jessie was also Mrs Dale in the radio soap The Dales (formerly Mrs Dales Diary).
There was also music to midnight from The Henry Mancini Orchestra.
