I went to a pub quiz tonight and as soon I got to the bar, a little man with a large pint started talking to me (not his first pint by the look of it). He was still there when we left several hours later and was regaling us with jokes. He was an affable character and said he had been in Coronation Street. Thanks for the replies - I have since found him and it was this guy https://en.wikipedia.org/wiki/Roy_Holder
