Hi there!! The Scottish actor who plays Tony Gordon is Gray O'Brien who has starred in a few programmes before including Casualty and Taggart (I thought I'd seen him before). Actually, I saw a back episode of Taggart the other night and he was on it, much younger of course!! I feel that maybe he is not really suited to this role, after all it is very different to Taggart!!
Btw, I do remember Len from "The Full Monty" haha!!
