Oh my god! They cut out the opening, where he comes out of the music box.
Camblewick Green, my childhood, cut!
I know this is favourite opening of yours, but it's so much better when one grew up with that intro as part of a children's lunch-time program.
A clever episode (aren't they all?) because there are sequences in which Sam is "unconscious" and not taking part. However, in the ostensible real world of the hospital room where he is a coma patient Sam has been over-medicated, so we can assume that he's having a dream-within-a-dream.
Or can we? Heh heh heh.
Yes! Dream/hallucination within one. (If that's what's happening - heh!) Like the flashback within a flashback.
