Yes, I was. We (19 Sqn) were hosting a party for our Danish F104 guests when they suddenly stopped drinking following a telephone call for their boss. We tried hard to find out why and they soon announced that they would have to return to Denmark. It transpired that they had been told about the Russian air transport movements before RAFG Ops were aware that anything unusual was happening.
Eventually our int boys got the message and we had to stop drinking too. Can't remember the hangover flying the next day but there were so many of them in those happy days.
