I have the older version where Tom Baker did his "Masterpiece Theatre" impression and the new one with full live-action and animation, finally telling the whole story. And even a proper credit (finally!) for Delia Derbyshire's theme for the show. Excellent.
Love Shada. It's genuinely one of my favourite DW stories. Never understood why Adams hated it so much (maybe it's just because the pet project that he'd originally wanted to do got refused and this had to be produced instead).
Interesting that some of the best bits are serendipitous. The chase sequence being in the daytime really adds to the feeling of Shada being flooded with light and freshness that the location shooting gives the serial and the vocal combo is another highlight that I'm surprised to hear was on a whim.
I very fondly recall a concert tour that the Choir of St John's College gave in Australia in the 1990's. It sounds like those involved handled the strikes and cancellation with incredible good grace and maturity. In their place, I'm not sure I could have done so. Tremendous accolades and gratitude towards everyone who eventually completed and published the story!
I've got a HD version of Shada on BluRay and it's absolutely fantastic, the missing portions have been made up with computer animation, the sound has been given a pseudo stereo remix and 5.1 Dolby Digital Surround Mix, the original BBC1 continuity at the start has been added and looks clean too, the Dr.Who theme tune has been given a surround makeover using the original elements and the electronic spangles have been found and overdubbed and the end theme is in 5.1 too with the original theme tune elements being stereoised as well and extended with 2 rounds of the middle-eight section plus complete roll-call credits of all the people responsible in the putting together and production of this new release.
