Having risen to many previous challenges here, this is one of the toughest ever. A few weeks of heavy training and preparation may allow the strongest ABers to obtain the gold star at the pinnacle of the pyramid.
Having missed the next to last series (yes, all of it) of Grange Hill as it wasn't advertised or on terrestrial TV, they began a repeat but cancelled it after the first episode as there were sensitive issues involved. I watched the dire final series but with such a massive gap could never work out how they got from one stage to another having missed the entire year except knowing the school bully was now the caretaker.
I've checked all the usual suspect sites for years and given up after clearly held back for some reason, but if I leave the request here maybe one day someone will turn up a method. I'd even pay for a series DVD as a last resort, at least I could finish seeing them that way.
Thanks Tony, I've just signed up, I've dragged up stuff from the 60s onwards over the years I never thought I'd see again so there's usually someone who's recorded them all and nice enough to share them.
