My point was that although he lived in London he probably didn't have to join the British army (he was Irish). On a personal level he must have felt it was necessary (he wasn't a gung-ho type - one of his ongoing themes was how crazy career soldiers were).
Coincidentally it's VJ day today.
I grew up on stories about his time in Burma and India. It's a pity that I can't remember any of them now. My dad once had an idea that he would record them, but I suppose that never went anywhere.
It's hard to say, but maybe those stories had some effect on me in my formative years that still live on with me today.
