On looking like "other people"

All through my adult life, I have "suffered" from being mistaken for other people. 

Friends and acquaintances claim that they have seen me in places where I have never been, that they waved to me from passing cars but I did not wave back, that they went up to somebody on the street and spoke to them - but they turned-out to be... somebody different. 

This is, I presume, due to having a somewhat nondescript face with rather indistinct features - a type common enough among grey-eyed, fair-haired, light-skinned, North Europeans and Scandinavians. 

It has also led (especially during the nineteen eighties) to people saying that somebody or another in the public eye looked "exactly" like me. 

For instance, Andy Partridge - lead singer of the pop group XTC: some giggling teenage girls on a train once thought I was him; and sang "Senses working overtime" at me, as I walked past.

Watching life of Bryan with friends, when the Michael Palin character who keeps saying "Crucifixion? Good..." came on screen, my pals simultaneously turned towards me claiming that he not only looked but was "exactly" like me:

Then was Ghostbusters, when Dan Ackroyd was another, supposed, lookalike:

And later still, Kenneth Branagh in the TV series Fortunes of War, was again "exactly" like me:

In later decades, there were no celebrity comparisons; just unfortunate bystanders and blokes in corridors, on pavements, in workplaces or social gatherings; who got mistaken and variously accosted. 

(At this point the problem was exacerbated by the fact that (due to baldness) I always wore a hat - preferably with a broad and shading brim. Any rubber-faced chaps in a big hat in Newcastle, might then expect to be assailed.) 

The moral is that some people look distinctive (once seen, never forgotten), while others Do Not - apparently I am, or was, one of the latter. 

And, with the advent of bogus "face-recognition" software - I suspect that my troubles are just beginning...
