By the summer of 1966, the Beatles sucked. Or at least that's the way they felt for the band. "Performance, for us, it's gone downhill," Paul McCartney said of his band at the time. "Because we can't develop if no one can hear us; so for us to perform...it gets difficult each time." The pressures of being the generation-defining, teenage-girl-arousing, million-dollar-making, international entertainment sensation was beginning to weigh on the aging pop group, evidently. Touring was becoming a drag: Playing to screaming girls who didn't care about the music, death threats from the KKK and Philippine soldiers, the bathroom being your only moment of refuge.
