This record seems to only be available in vinyl format now I'm afraid. However, I did find the following CD (3 CDs in one case) which has many of the songs featured on this album and much more..... http://www.amazon.co.uk/Hello-Children-Everywhere-Various-Artists/dp/B00030 B9K2/ref=pd_sim_m_h__1
Hopefully it covers all from your favourite album. If any are missing you could try downloading those as individual tracks.
Hope that helps.
