"42 Up" and the Up documentaries

[Milz]

My PBS station televised "42 Up" last night. I never saw the previous 
documentaries, but I found the program to be fascinating. However, 
yesterday was very hectic at work and I unfortunately fell asleep in 
the middle of Paul's segment. Did anyone watch the program? I 
understand it was aired in the UK in 1998 or 99. From various reviews 
I've read, one of the people, Neil, is supposed to have had a major 
transformation. Can anyone fill me in? I can't seem to find any 
detailed summaries of the documentaries on the web. And my PBS 
station as of yet has no plans to re-televise the program.
