Russnet must be russel brand himself!. I Think the generalisation was intended. If you look at that show on sky one pop years, there are a few dodgy z listers that appeared on it. Anyway, The Rock n Roll Years differed so much because sometimes the star of the show could be a member of the public.
Perfect example, The 1974 episode featured some clips of the 1974 general election, the end of three day week etc. Members of the public were asked did they know what were the main issues that the election of a new government would have to concentrate on. A few people said they didnt know, or that they werent sure, but this one man commented "well it's housing and rising costs of the food.....well its got to be aint it".
There was a strong reference in that years episode of food shortages, i.e bread shortages and sugar shortages. So this man was right although it is the way he says this which is funny.
