I put the Holiday Special on yesterday. I haven't seen it since about 1994. And I have to say it makes me cringe so much. It's like watching a film where all the stars are contracted to do it and clearly non of them want to be there and are just going through the motions. (is this the case?)
I must say I don't really know much about the 'why'.
Also, lets hope that the make-up artist on the Holiday Special is no longer in the business. Did they own shares in an eye-liner company?! Blimey!
