Andrew Neill's hair has changed dramatically since his spitting image days. It did look like a brillo pad then, but now it is completey straight as well as being much more substantial and a totally different colour.
I remember a chap at work who was suspected of having a syrup, he was in his 50's and had straight dark brown hair cut rather strangely. One of the girls decided to find out the truth and deliberately tripped over near him and clung on to his head to prevent herself falling over. Sadly his hair was real though she said the roots were grey
