I remember these well. Always on the rack in the Newsagents along with Night of the Crabs & Killer Crabs. Bless The New English Library.
I bought Night of the Crabs a couple of weeks ago while in Deptford with the Time Attendant funnily enough. Read it on the train in the way home. It's a bit rapey.
I am afraid I did not learn my lesson with the 1st one. I ended up getting Killer Crabs and The Origin of the Crabs. Really enjoyed the Exotic Pylon show you did with the Time Attendant.
Gosh thanks - it was a bit slapdash. But made better by playing Pye Corner Audio...
