Here is an unmarked Emidisc acetate of what sounds to be an early 70s or very late 60s outfit with definite progressive leanings. In fact it is virtually a progressive primer, covering a lot of ground in just over three minutes.
Question is -Who is it? Was it released? If so -Is it the same version.
The fairly extensive use of mellotron say 69-71 to me, and the music sounds a bit like Audience / Greatest Show On Earth or Galliard.
Perhaps it is a well known released track -in which case I will remove it. My progressive knowledge is somewhat sketchy.
For what it is worth - here is a picture of the acetate. It is one sided and has nothing written on it at all.
