Can anybody help me identify find a British 1960's army training ground comedy which contains the words to the effect that 'the army has sunk pretty low but not so that its music is played on a spittletrap'. Also at the canteen somebody complaining about the food said 'but beautifully cooked' to protect his friend who was on cooking duty. Would be very grateful! It is not 'Carry on Sergeant' which I've already got in my collection.
