do we know if this was actually illegal though i do not know either way but is it possible steve was allowed to keep his working copies to do with as he pleased again i do not know but this very well might be possible acetates and such regularly turn up on ebay and these were once in the hands owned by the engineers band members etc working copies in and of themselves do not imply copyright ownership similar to one buying a mm film print but usually one is allowed to have working copies of one's work and do with them as they please however the rights to the underlying works are not transferred but the object in this case a cd can be given or sold
