Captain Birdseye, as far as I know, Dick Hall did some unacompanied singing (e.g. the stuff he sang for Gardiner) and he was much in demand for his "humourous ditties" which are mentioned in occasional reviews in the Hampshire Chronicle, without reference to an accompanist (though that doesn't mena that there wasn't one, of course). I how don't know how the balance of material would have worked out so can't really help there.
