In the early 1980s, a radio station here in Winnipeg aired the two EarthSearch series. In true Canadian fashion, they aired the second series first. I was captivated by the story, and at the time I sent a letter to the BBC asking if this series could be purchased in any form. Getting a negative response from them, is tas in the late 1990's that I tracked down the cassettes the BBC sold of the series. Unfortunately, even this was somewhat edited. So when this particular series came out, I was basically praying that it would be unedited and sound as good to me now as it did back in the early eighties. I was not at all disappointed. The addition of some commentary from James Follett is a welcome bonus, and I am very grateful for this long-awaited CD release of a wonderful BBC series.
