The song is taken from the 1969 album “An Electric Storm” by White Noise. The group started as a project between members of the notorious (not only for the Dr. Who theme) BBC Radiophonic Workshop. Among the composers who worked with David Vorhaus on the project was Delia Derbyshire. The state of the art tape manipulation techniques that were used on the album result in a highly psychedelic listening experience (similar techniques have been used on Sgt. Pepper’s Lonely Hearts Club Band, but not to the extend that can be found here).
Enjoy!
