Thanks Danny,
I think you got it "was he on disembarkation leave on VJ Day ?". Such matters were not explained to a 7 year old.
I was staying with my Uncle and Aunt in Cricklewood when I was woken at I think about 10.15 p.m. by train whistles, vehicle horns, shouting (and fire works?) whether I dared get up or waited until breakfast to ask what all the noise was about. Anyway the answer was "its all over", dim me needed more explaination.
I remember my Uncle took me everywhere and he was very smart in his uniform. On the buses we generally traveled free or for the minimum fare (I expect this was so there was a ticket to flash at an inspector)
