Shake and Blake - Episode 26

Ian and Dave return with a mixed bag of Blake's 7 this month. In
"Sand," the Scorpio crew and Servalan travel to a planet which
might contain a valuable new resource. The resource turns out to be
sentient sand with a rudimentary knowledge of basic farming
techniques. Can the crew overpower evil sand? Why are we even
asking that question? In "Gold," an old acquaintance of Avon's asks
for help to steal a fortune in gold from a luxurious cruise ship,
but who is really pulling the strings? They also discuss Tarrant
acting stoned, the actor Peter Craze, Dave gets to channel Marvin
Gaye again, and who in their right mind would think that an episode
where the villain is some sand was a good idea?
