OK, I’ve been helped out by a fellow fan who has identified the subtley different intros used for season 2 (the difference is VERY subtle!). The Blu-Ray release is accurate in this respect so no work required.
I am however still on the lookout (or should that be listen out?!) for the 2 stereo episodes listed above. If anyone can assist with this please let me know.
Also any edits to the BluRays that I haven’t listed.
Thanks
