The Ice Warriors invade the human's base, and it is up to the Doctor to repel them. Using the ioniser is the only way to defeat the Martians, but to do so could have consequences.

BBC Radiophonic Workshop return to their spiritual home Maida Vale for their set tonight. How excited do you think Marc is over this live session from these true legends?

The BBC Radiophonic Workshop, set up in 1958, it as originally created as a sound effects unit for BBC Radio and TV programs. Pioneering new forms of drama during the late 1950s and early 60s demanded innovative and original use of music and sound which they'll be bringing to our show tonight - Yes.

If you needed a bit more of a tease - yip they'll be doing a re working of the Dr Who theme.

Ronald Allen was an English character actor who achieved the status of a soap opera star.

Allen was born in Reading, Berkshire. He studied at Leighton Park School in Reading and trained at the Royal Academy of Dramatic Art (RADA) in London, worked in repertory theatre, had a season at the Old Vic, London and made several films, including the classic about the sinking of the Titanic A Night to Remember (1958).

After roles in the BBC soaps Compact (1963-64) and United! (1966-67) came his best remembered famous role, in the long-running Crossroads (1969-85). Allen played David Hunter, who was a shareholder of the Crossroads Motel with Meg Mortimer, Tish Hope and Bernard Booth. He also twice appeared as a lead actor in the science fiction programme Doctor Who, in the storiesThe Dominators (1968) and The Ambassadors of Death (1970).

Allen also made a number of guest appearances in The Comic Strip Presents. In the first episode, Five Go Mad in Dorset (1982), which spoofed Enid Blyton's The Famous Five stories, he makes a surprise appearance as Uncle Quentin; deliberately sending up his staid image, he most memorably told The Famous Five, "Your Aunt Fanny is an unrelenting nymphomaniac – and I am a screaming homosexual". (The show's TV Times entry had listed him as "Surprise Guest"). Allen reprised the role in the sequel Five Go Mad on Mescalin (1983), and also appeared inSouth Atlantic Raiders Part 2 (1990), The Strike (1988) and Oxford (1990), in addition to the feature film The Supergrass (1985). There was much comic mileage to be gained from Allen sending up his conservative image. In a 1987 interview, he said that he was approached by a very intimidating-looking punk. He shook his hand and said, "I thought you were really cool in The Supergrass". Then, as he was about to walk away, he turned back and said, almost apologetically, "I loved you in Crossroads too!"

Other roles included television's The Adventures of Robin Hood (1957), Danger Man (1960, 1961), Bergerac (1990) and The Avengers (1964).

Allen lived for many years with the actor Brian Hankins, who also appeared in Crossroads. He was also very close friends with his co-star and on-screen wife, Sue Lloyd. When the British media started to intrude into their private lives, they made it known they were a couple. After Allen was told that his cancer was terminal, they married. He died three months later, aged 56 or 60.
