Its funny to have this in place as I recall productions at the BBC having to be re-recorded to VT as the audio talk back from the gallery was much to audible when played back to be used for TX.
Some early Hartnell Doctor Who episodes from 1964 gave a lot of problems with this.
I am pleased this exists in the BBC archive, however I would have loved 'Beach Head', “Get Off My Cloud”, “The Yellow Pill” and all of “The Little Black Bag” to have survived the tape wippings of the 1970's.
