As a result the Queens and Regimental (with the crown on) colours were taken out of mothballs.

So on the final parade on 17 October 1980 both colours were paraded.

See both colours on parade here:



The men of the battalion were proud to parade the Queens Colour but would have gladly chopped the vermin who infested the corridors of the British Foreign and Commonwealth Office into little bits.
