They decided to have what would now be called a brainstorming session at John's house. According to Hunter Davies, this was a bewilderingly casual event in which they spent much of the time flicking through magazines. From time to time they would sing out phrases or pick out bits of tunes at the piano. Ian Macdonald speculates that there was some method at work in that 'both writers 'found inspiration in moments where their conscious minds had fallen into abeyance.' Whatever the strategy, it worked. By the end of the day McCartney had a new song, 'The Fool on the Hill'. Lennon, meanwhile, plugged away at the chords to a tune with the working title Badfinger Boogie. This reflection on on a minor injury would eventually became better known as 'With a Little Help From My Friends'
