I do remember being disappointed on viewing the DVDs, that there was a sequence with The Guv driving The Cortina across wasteland to where some kids had dicovered a murder victim. Disappointed because the original broadcast version was backed by 'Lay Down' by The Strawbs, which to me fit perfectly. On the DVD the scene was backed by a track by The Moody Blues, which was quite different. I know there's all sorts of release/copyright issues etc, but this one seemed a bit glaring in that the replacement track was of a completely different style and 'feel' to that originally used. Minor point though.
Whit sad old loser'd be thick enough to don thon get-up?
From what I can see from the song lists,there are several songs were replaced.For example "Stairway To The Stars" by Blue Oyster Cult was replaced and "Feel Too Good" was used instead.
