Slipback (audio story)

Slipback by Eric Saward was the first original Doctor Who serial to be produced for radio. It was first broadcast by BBC Radio in the summer of 1985 when the televised series was on hiatus for a year. Colin Baker and Nicola Bryant reprised their TV roles for the production, which also included other cast members. It, along with the earlier Doctor Who and the Pescatons, is considered a forerunner of the later Big Finish Productions audio dramas. It was followed nearly a decade later by two more radio dramas starring Jon Pertwee and in 2007 by a new made-for-radio series for BBC7 (produced by Big Finish) starring Paul McGann.

Slipback was released on cassette by BBC Audio, and later on CD by Silva Screen Records.
