Sir Paul decided to record the album "live in the studio," meaning that the band would rehearse an entire song then record it in one take, instead of recording each vocal track and instrumental track separately. This approach gave a new, raw and direct feel to the work. His increased interest in social issues came to prominence on this album, with the anti-animal cruelty rocker 'Looking for Changes,' or paeans for a better world ('Hope of Deliverance' and 'C'mon People'). This is an important album in the McCartney catalog of music, and is a pivotal addition to all McCartney music collections, and Rock music collections in general.
