Yes it does bring back many happy memories, particularly of the war years. I lived near an airfield and my Mum and Dad had two airmen billeted with us. Even at that tender age I could sycopate the lefthand on a piano and was regularly asked to play this tune. (No! I'm not going to tell you all how many moons ago that was. Suffice to say "I am as old as my tongue and a little older than my teeth") - now you work it out.... ha! ha!

Thanks again everyone for your help.
