the child actors in that advert were Carl Rice and Kevin Staine. But co-incidentally, one of the 1st team regulars who took Accrington back to the FL is called Robbie Williams.
Robbie Williams did do the old Yellow pages Ad though. The Christmas one where the little boy (RW) piles the directories so he's tall enough to kiss the little girl under the mistletoe.
Thats not Robbie Williams - dont know his name but read an article about him in the newspapers a few years ago - he is now about 21 and yet he is immortalised in that advert for eternity
