I'd assure people that, no, they really didn't look like a twat when they did that, or when they sang with a fag in their mouth.

Clapton may have been able to get away with it, or the Swarb with one in his gob whilst playing one of his matchless solos (see what I did there?), but, in my humble opinion, most other people just looked like tossers.

And working, as I do, in oncology, I expect that at least half of those that did it in my youth will now be dead or of concern to colleagues of mine.
