These discs are of excellent sound quality and present a great selection of material. While they don't contain as many versions and takes as the Backtrack series, there are a lot of important tracks here. The sessions for Strawberry Fields Forever on Volume Three are fascinating and presented in excellent sound quality. The Peter Sellers Tape on Volume Four is quite interesting and the early versions of the Abbey Road medleys on Volume Five are great. The 'Think For Yourself' session recording on Volume Seven is amazing. A must for collectors! Highly recommended.

This disc is of particular interest because of the final track, taken from the 'Think For Yourself' sessions. I've heard snippets of this on other boots, but this is the full version. The band recorded themselves chatting and rehearsing vocal tracks for this song in hopes that they might get some funny material on tape for their Christmas Fan Club Record. Portions of these recordings were later used in the Yellow Submarine movie soundtrack. A fascinating recording that reveals how much fun the band had during their recording sessions.
