Query: Mediocre at best

Talk about mediocre song writing! John Lennon was right when he proclaimed McCartney's post Beatles work as pretty bad. The release of this album was in part due to McCartney's ego, he believed he was a genius and could do no wrong. This album proves otherwise. Also, being high almost all of the time had caught up with McCartney and almost everything sounded good to his deluded senses.
