Having purchased this release it has to be said that the sound quality is not the best - but if one considers the age of the tape from which it originates that is not surprising. The tape was found on an old reel-to-reel tape recorder which had been lent to Paul McCartney and was passed back to the owner with the tape still on it, and was then put into a loft and forgotten for over 3 deacdes before it resurfaced and was sold. Interesting to hear early versions of One After 909, but most of it is only for the hard-core fan who has to be a completist. The CDs have some information on the cover but is not really informative.
