Personally I felt the 50 Years of BBC Two Comedy was spoilt a bit by the 'talking heads'. Whilst having some was perhaps inevitable a lot of the time the people weren't directly related to the programme/clip being featured, and therefore arguably unnecessary. I thoroughly enjoyed Harry & Paul's Story Of The 2's though.
