Blake’s 7 series four

Thomas and Knyvette left at the end of series two, replaced by Tarrant (Steven Pacey) and Dayna (Josette Simon). The Liberator was destroyed at the end of series three, and Cally died on the planet Terminal. For series four, a new ship was introduced – Scorpio – along with a new computer, Slave, plus new team member Soolin (Glynis Barber). Thomas returned as Blake in the final episode, tx 21/12/1981, in which the entire cast was massacred in the closing scene. The credits rolled before we saw Avon’s demise… did he survive?! The title music for series four was given a jazzy re-arrangement by composer Dudley Simpson.
