Gives me shivers thinking about it now it's such a brilliant piece of TV, definitely one of the finest bits of TV I have ever seen and, as you say, gets a tear or two going at the end.
Just finished watching the first three series on Netflix and loved it, especially '12 Days of Christine' and 'A Quiet Night In'. Live special was good to. Completely missed out on this when it was on first time round, don't know why I didn't pick up on it more as I really like 'Psychoville' also.
