We report observations of variability amongst the stars of the ``Quintuplet" cluster located about 30 pc in projection from the centre of the Galaxy. Two of the five cocoon star members, which may be protostars or peculiar Wolf-Rayets, are seen to vary slowly with moderate amplitude (0.4-0.5 mag). The bright star within the ``Pistol" H ii region, suspected of being a Luminous Blue Variable (LBV), has in fact been found to show variability, confirming its tentative classification. A second nearby presumed LBV also varies. One of the apparent Quintuplet members is likely to be a Mira variable along the same line of sight.
