I also very much enjoyed the television program. It very much makes a difference when you have a presenter such as Howard Goodall who can not only tell you about such and such a piece but further enhance what he says by playing an example.
Not sure I would rank Sgt. Pepper as one of my all-time favourites but came to the conclusion long ago that I cannot really objectively analyse the Beatles' music as they were such an integral part of my pop-saturated youth. (well, I can, I suppose, if really pressed.)
One of the biggest revelations for me from the program was that the song "LS Bumblebee" was done by Peter Cook & Dudley Moore. I remember that being played and announced as a Beatles' song when it first came out. For years I talked to friends about this 'lost' Beatles' song - and got a lot of funny looks. I cannot believe that, over all these decades, I never knew the truth!
