Eight Days a Week
Originally released on the U.K. album Beatles for Sale, this song was issued as a U.S.-only single, as well as on the American LP Beatles VI, in 1965. And although its reaching Number One marks its classic status, co-writer John Lennon did not share that assessment of the track. "We struggled to record it and struggled to make it into a song," he said in 1980. "It was [Paul McCartney's] original effort, but I think we both worked on it. But it was lousy anyway." McCartney has given two explanations for the title at different times: The first is that it was an overworked chauffeur’s response to Paul's question about how many days he'd been driving; the second is that it was one of the many elliptical "Ringo-isms" Ringo Starr would come up with, alongside "a hard day's night" and "tomorrow never knows."
