I should amend my 08 Feb 11 - 01:54 PM post to say it's not clear whether any of the performances were unaccompanied. The omission of info on accompaniment doesn't mean there wasn't any... Llewelyn Lloyd says in his review about the Kenneth Ellis recordings on Parlorphone that "the accompaniment is provided by a string quartet and flute, which proves a pleasant change from the usual pianoforte".
