Blurb:
At last it can be told!!! The true story of the world's most fabulous man...Captain Kremmen!
Within these pages, Captain Elvis Brandenburg Kremmen, displays the kind of raw masculinity and butchness that makes grown men rasp with envy and women faint at the very mention of his name...
From his early beginnings at school, putting paid to bullies and sorting out class rotters, to zapping across the universe to deal with invasions...those many-headed, quivering lumps of walking doom...The Krells!!!
...join our hero inside and feel that rare thrill of electric excitement runnin' up yer doobrie....
WARNING: the book contains two very racists scenes which are not in any of the original radio plays. It seems likely that these were created by the writer, Chris Browne.
