I know that one track indisputablely recorded by Alan Lomax, and in the fashion of the times exchanged with Peter Kennedy, is despite polite protests still planned for inclusion in the new releases, and asserted to be co-recorded by Kennedy while he was hundreds of miles away.
And I have in recent years seen offered for sale on the Internet several CDs worth of other Lomax recordings - including ones I recently learned Lomax had in turn copied from BBC recordings [not made by Kennedy].
This discussion has been, fair enough, dominated by one recording, but as other discussions confirm he was at it all the time. He did great things, sure. That's no excuse.
