With the help of Rodney Mark Davis, I've managed to get hold of a copy of Dick Hyman's 1966 Command LP "Happening! Dick plays harpsichord on this album and the tracks include his interpretation of "Lady Fingers" (sic) - a very different version to Herb's. Keep an ear out for it on 'The Lively Lounge' but also keep an eye out for a second hand copy. they seem to be very rare but worth having.
