Isn't there a discrepancy over dates here? Zammo died in 1987, Stenders started in 1985, and Ian was only a whippersnapper then. However I've just checked on IMDb and no it isn't.
i don't think anybody understands me there was a boy who played peter beale before they replaced him with the actor that plays him now, he looks the spitting image of Zammo from grange hill and i wanted to know if he was his real brother,, IN REAL LIFE
I know what you mean too but as the actor who played Peter Beale before the cureent one probably wasnt even born til the 90's, I very much doubt it. The actor who played zammo would be old enough to be his dad!
