I've already planned to use two tracks from this in my science lessons and for the harvest assembly, but when I went to get the CD it was the wrong CD in the case and I cannot find the 'That's Science' CD anywhere!!! I used to have it backed up on my laptop, but the laptop crashed a few months ago and I hadn't backed up all my school music as I had the CDs anyway..... The book & CD seems to be totally out of print now (I bought my copy about 7 years ago) and I can't source a new or second hand one anywhere . Can anyone help??
