One big disappointment actually.
They have simply taken the version that has been circulating on the internet since 2009/10 and edited bits out, particularly towards the end where the tape sounds like it has been chewed up.
They have also removed some of the lyrics, and in a fairly shoddy way.
The best example is the bit in the original demo where Moz sings and when you are dancing and laughing, living and loving, which has now been edited to and when you are dancing and laughing and loving.
It's a real shame, I was looking forward to listening to this particular recording in pristine quality. I guess such thing does not exist, so they have used the best available source.
