The first "Doctor Who" audio production, released on LP record in 1976, was a children's adventure entitled "Doctor Who and the Pescatons" by Victor Pemberton. Around this time an audio version of the televised serial "Genesis of the Daleks" was released on record, with specially recorded narration by Tom Baker. Both of these early releases have since been reissued on CD. The same year, Tom Baker and Elisabeth Sladen reprised their roles in an episode of the BBC Schools radio play .
