Paul was the lighter, happier side of the Lennon / McCartney songwriting duo, while John was the grittier, brasher side. When you mixed the two, you got magic. But when these two seperated, you got soft, fluffy songs from McCartney, and angry songs from Lennon. Band on the Run is good McCartney, that little gypsie band running here and there and playing little gigs and just as happy as can be. It's a good album, and it contains some of Paul's better songs, but it can't quite shed itself of that bubble gum sound.
