Oh, I found it fascinating - how the longer playing time the 12" LP could afford, allowed musicians to break away from the 2 -3 minute pop single constriction. And the battle to have radio stations embrace LP tracks.

Agreed the emergence of the 'concept album' was a little muddled (with that of the so-called 'Rock Opera').

I expect most viewers watching the programme said to themselves "Hey I've got that one - and that one - and that one". And possibly "Oh no - that one was a load of crap!"
