I must say,though, that the Murraymints advert with the Guards sergeant-major going purple with rage was, to me, quite funny. For those who haven't seen it, the characters were conveyed by a primitive form of animation.
I'm sure Coachmann and others of our age group will remember "The Esso sign mean happy motoring", which ran for years.
They weren't annoying, often quite tuneful, whereas most of the modern adverts are annoying or just boringly dull, especially those current retro-themed adverts using a Yankee voice.
