This was originally released in 1979 on vinyl and cassette and I would regularly see it during my visits to WH Smith on a Saturday morning with my dad. In June 1980 on a holiday to Blackpool my dad came back to the hotel with it on cassette for me and as he'd brought a portable cassette player with him I was able to listen to it before we went home.
We are spoilt in the days of DVD and the internet in that we can watch almost anything anytime. Back then your only chance to relive a Doctor Who adventure was with the Target novelisations but to have a story to listen to was a dream come true. It even had the theme tune to introduce each "part" (Genesis is a six part story and this was only two parts).
It is very edited, it has to be condensing a two-and-a-half hour story into one hour but it works brilliantly because all the main parts that make the story so good are there and I listened to this recording so many times over the years. It eventually got lost I reckon but to have it again on CD with the original cover, I really cannot wait to hear this version again. I bet I can still remember it word for word.
