During the 1960s, music fans would always anticipate the latest single from The Beatles, who were taking the music industry by storm. The single’s A-side was almost guaranteed to be a hit, with the B-side usually landing with mixed results. However, Paul McCartney said The Beatles always tried to deliver excellent B-sides, even if they flopped.
The Beatles had many excellent A-side singles like “Hey Jude” and “Can’t Buy Me Love” that dominated the charts in the 1960s and are still widely listened to today. However, there are a few deep-cut B-sides that many people, including The Beatles themselves, believe are better than the A-side they were on. A few examples of these include “I Saw Her Standing There”, “I Am the Walrus”, and “Rain”.
“Rain” was released as the B-side to “Paperback Writer”. “Paperback Writer” was a No. 1 single, but The Beatles thought “Rain” was the better song. In the book The Beatles: Off the Record, Ringo Starr said “Rain” is one of his favorite Beatles songs and said it’s the best piece of drumming he did with the band.
