But the mania had proved too manic for the Fab Four in the months leading up to the gig. Deafening (and non-listening) audiences, pushy promoters and local bigwigs, angry record-burners (following Lennon's infamous "Bigger than Jesus" comment) and a near riot in the Philippines had convinced the boys — even the ever-enthusiastic showman McCartney — that enough was enough. The circus had to stop.

There were also the band's musical ambitions to take into account. Emboldened by their ever-growing songwriting talents and energized by advances in studio recording technology, they would no longer accept the three-songs-in-a-day-squeezed-somewhere-between-tour-legs approach to recording. They wanted time to build layers upon layers of musical constructs that, themselves, would be too complex to ever reproduce on stage. Case in point is the band's set list from the 1966 tour, which included not a single track from their most recent album, Revolver.
