Today I dusted off The Beatles' Magical Mystery Tour for the first time in awhile. Going back and forth between John Lennon and Paul McCartney's songs--the segue from "Strawberry Fields" to "Penny Lane", for example--it really makes me wonder what these guys thought of each other at this point in their careers. McCartney is often unapologetically romantic, owing more to Cole Porter than Elvis, while Lennon is usually more mysterious and gritty. (As I say this, though, it's with hesitation, because I get so sick of them being stereotyped this way.) I know they are listed as co-writers of both their tracks, but clearly each guy was bringing very different songs for the other to see. So did McCartney and Lennon have to mask their skepticism about each other's songs and just try to make them better? Or was each guy really a fan of the other's style?
