The single reached the top of the British charts on 12 December of that year, displacing The Rolling Stones' "Little Red Rooster", and remained there for five weeks, and the top of the Billboard Hot 100 in late 1964. The B-side was the #4 hit "She's a Woman".
"I Feel Fine" was the last of six Hot 100 #1 hits in a calendar year, a record at the time, and also the first of six Hot 100 #1 chart toppers in a row (not counting the EP "4 - By The Beatles") by one act, also a record at the time. The subsequent singles were "Eight Days a Week", "Ticket to Ride", "Help!", "Yesterday" and "We Can Work It Out". The latter record was equalled by The Bee Gees in 1979 and surpassed by Whitney Houston in 1988. "I Feel Fine" was also the first Beatles single to be released almost concurrently in the US and the UK.
Lennon wrote the guitar riff while in the studio recording "Eight Days a Week". "I wrote 'I Feel Fine' around that riff going on in the background", he recalled. "I told them I'd write a song specially for the riff. So they said, 'Yes. You go away and do that', knowing that we'd almost finished the album Beatles for Sale. Anyway, going into the studio one morning, I said to Ringo, 'I've written this song but it's lousy'. But we tried it, complete with riff, and it sounded like an A side, so we decided to release it just like that."
