Copies of the VHS were given out at an event to celebrate Nemesis’ 10th year in 2004, and I am sure on other occasions too.
I still have a copy, signed by John Wardley from the Nemesis X event. Don't have a VHS player though.
That event was brilliant though. I think it was quite cheap for what we got, it was under £200 for a room for two of us and we got to use the water park on arrival day, dinner in the Emperor room with a talk from John Wardley and Andy Hine, a night in the hotel, then exclusive ride time the following day with Air & Nemesis followed by Oblivion and then Corkscrew, with complimentary coffee & pastries at Refresh@ripsaw and then hotdogs & soft drinks in Ug Land.
Most people attending either were RCCGB members, Alton Towers Almanac forum users or Rideas members, as Andy Hine organised games against each group after the talks!
We shared a table with Russell Barnes, the park manager at the time who had just moved to the role that week so going for dinner with the geeks was probably quite a shock! Of course RCCGB members asked the director (I forget his name) and John W about the cross-valley woody plans.
We re-rode Nemesis several times without getting off while Andy Hine did a piece to camera on the ride for Midlands Today and then later on they were filming us on Corkscrew for another documentary, staying on Corkscrew for eight or so cycles was quite painful though!
I don't see AT putting on this sort of fan event again and also it would probably sell out way too easily nowadays.
