John Lennon (in 1972) - "Me. But I think Paul helped with the verse."
John Lennon (in 1980) - "That's mine. Including the guitar lick, the guitar break, and the whole bit. It's just a rock 'n roll song. Day trippers are people who go on a day trip, right? Usually on a ferry boat or somethng. But it was kind of-- you know, you're just a weekend hippie. Get it?"
Paul McCartney (in 1994) - "Acid was coming on the scene, and we'd often do these songs about 'the girl who thought she was it.' Mainly the impetus for that used to come from John-- I think John met quite a few girls who thought they were it... But this was just a tongue-in-cheek song about someone who was a day tripper, a sunday painter, a sunday driver, somebody who was committed only in part to the idea. Where we saw ourselves as full-time trippers, fully committed drivers, she was just a day tripper. That was a co-written effort-- we were both making it all up but I would give John the main credit."
