Yes, Jag,

I'm thinking the 'property if theft' thought may be there.

Also I fully acknowledge deep unease about the way, say, that the Lomaxes (and, some people argue, Peter Kennedy) copyrighted material they collected.

I did read something from Mayhew by a poor chap who made a small bit on money selling verses to broadsheet printers: that sticks in my mind.

Is there also some feeling that 'work' has to be manual, not mental, to count as 'proletarian', or is this a red herring?
