More 1984 group pictures. A number of
pictures were taken with my camera at the time of the
same photo shoot as the two pictures by David Dyer-Bennet above. In
fact, ddb himself is seen in a couple of these setting up his shots.
These scans are from the original negatives and pretty well capture
all the resolution they have.
