Sid was in quite a few of the original TV shows, but not all. It later turned into something of a two hander. It is a shame that the Jacques and Williams characters will not really appear regularly again, although in one or two. There is another Jacques appearance in Lady Chatterley's Revenge which would be great. But with the cast possibly taking on other parts it would still be very interesting. I could easily see Eldon appearing in Emery, Frazer or Mitchell roles. You have the problem of finding actors who can take on roles played by people of the calibre of Liz Frazer etc. The real oddity and gem, the Holy Grail of missing shows you might say is The Radio Show. This featured Spike Milligan, Eric Sykes and Graham Stark. I am sure though, with the kind of attention detail and a little tinkering here and there this would be an interesting and worthwhile project, especially as idiotically they have cancelled the radio show, which doesn't bode well, and we probably end up with Are You Being Served instead
But you never know - a dear late friend of mine, who had one of the first reel to reel tape recorders in the UK used to save some of Hancock and the Goons, and one of the Hancock's was the odd ball "Blackboard Jungle", which was a lost episode at the time when he gave me a copy of it.
Could the "Bible" be wrong? Roger Wilmut's "Tony Hancock Artiste" quite clearly shows Sid as not being in the first two TV episodes of Series Two, but then is shown as being in No.3; but not in 4 (The New Neighbour) or in 5 and 6.............BUT THEN doesn't list The Lad Himself after episode 3 either.
