John was never closer to Paul than during these weeks. Though hotly competitive in songs they wrote individually outside the studio, they remained a matchless team within it, each working unselfishly to set off the other’s latest brain wave at its best. Paul composed a piping intro for Lowry organ that established the drowsy riverbank atmosphere of “Lucy in the Sky with Diamonds” before John had sung a word; he also contributed to the lyric, supplying “Cellophane flowers” and “newspaper taxis” to set alongside John’s “tangerine trees” and “marmalade skies.”
