The Penny Dreadfuls Present... is a British radio comedy programme, written and performed by comedy troupe the Penny Dreadfuls, with each episode looking at a different member of The Brothers Faversham, a collection of heroes of Victorian Britain.
 The first series was produced and broadcast by the BBC for BBC Radio 7 and aired between January and February 2008.
 The second series was broadcast in October 2008, and was repeated on BBC Radio 4 in December 2008 and January 2009.
 An episode on Guy Fawkes was broadcast in BBC Radio 4's "Afternoon Play" slot on 5 November 2009.
Julian and Sandy were characters on the BBC radio comedy programme "Round the Horne" from 1965 to 1968 and were played by Hugh Paddick and Kenneth Williams respectively, with scripts written by Barry Took and Marty Feldman.
 According to a BBC Radio 4 programme on the characters, they were named after the writers Sandy Wilson and Julian Slade.
The Fraser Hayes Four, originally called The Fraser Hayes Quartette was a British close harmony vocal group, formed by the musicians Jimmy Fraser (real name Frazer Potts) and Tony Hayes in the late 1940s, disbanded in 1953, and re-formed in 1956.
 According to 'The Ballad Years' by Don Wicks, the four original members were Jimmy Fraser (Potts), Tony Hayes, Dave Mason and June Ellis.
 The group split for good in late 1969.
 They are best known for providing musical interludes on the BBC Radio comedy programmes "Beyond Our Ken" and "Round the Horne".
Round the Horne is a BBC Radio comedy programme that was transmitted in four series of weekly episodes from 1965 until 1968.
 The series was created by Barry Took and Marty Feldman, with others contributing to later series after Feldman returned to performing, and starred Kenneth Horne, with Kenneth Williams, Hugh Paddick, Betty Marsden and Bill Pertwee.
 The show's announcer was Douglas Smith and from time to time he took part in the sketches.
 It had musical interludes by close harmony singing group the Fraser Hayes Four, and accompaniment by the big band of Edwin Braden ("the great, 'airy fool" according to Kenneth Williams), known as Edwin Braden and the Hornblowers.
 The band was actually the BBC Radio Orchestra but was never billed as such.
 In the fourth series, all the musical duties were performed by the smaller Max Harris Group.
 Took and the cast had worked on the predecessor series "Beyond Our Ken".
 The name is a pun on the nautical phrase for sailing around Cape Horn.
Denis Mostyn Norden, {'1': ", '2': ", '3': 'CBE', '4': "} (born 6 February 1922) is a retired English comedy writer and television presenter.
 After an early career working in cinemas, he began scriptwriting during the Second World War.
 From 1948 to 1959, he co-wrote the successful BBC Radio comedy programme "Take It From Here" with Frank Muir.
 Muir and Norden remained associated for more than 50 years: after they stopped collaborating on scripts, they appeared regularly together on radio panel programmes "My Word!
" and "My Music".
Take It From Here (often referred to as TIFH, pronounced — and sometimes humorously spelt — "TIFE") is a British radio comedy programme broadcast by the BBC between 1948 and 1960.
 It was written by Frank Muir and Denis Norden, and starred Jimmy Edwards, Dick Bentley and Joy Nichols.
 When Nichols moved to New York City in 1953, she was replaced by June Whitfield and Alma Cogan.
 The show is perhaps most famous for introducing "The Glums".
 Through "TIFH" Muir and Norden reinvented British post-war radio comedy — amongst other influences, it was one of the first shows with a significant segment consisting of parody of film and book styles, later used extensively in programmes such as "Round the Horne" and many television programmes.
And Now in Colour was a radio comedy programme that aired on BBC Radio 4 for two series (each consisting of six half-hour episodes) and two half-hour Christmas specials between March 1990 and December 1991.
 It starred Tim Firth, Tim de Jongh, Michael Rutger and William Vandyck and has since been repeated on BBC Radio 4 Extra, most recently in 2016.
