What it actually says on the back of "The Dunmow Flitch" is:

"Copyright exists in all recordsissued by Sweet Folk All Recordings Limited. Any unauthorised broadcasting, public performance, copying or re-recording of such records in any manner whatsoever will constitute an infringement of such copyright. Application for public performance licenses should be addrsssed to ...."

so it is obvious that permission has to be asked for the recording to be played in public, but elsewhere there is, let us say, a slight touch of ambiguity.

PS. I bought my copy from Dick himself at the Willoughby Arms in Kingston.
