With a few exceptions at the end of their career, the Beatles did not include songs that had previously been released as a single on their UK albums. According to George Martin, The Beatles’ Producer, “At the time, I didn’t want to shortchange the public. Assuming the fans had bought the single, I figured they wouldn’t want to hear it again on the album.”
Although this approach was common in the UK, it ran counter to the then current Conventional Wisdom in the US music industry. However, by the release of Sgt. Pepper, the Beatles had gained complete control over their creative works in the US and curtailed Capital Records’ prior practice of including singles on US albums.
This tactic provided the Beatles with a strategic advantage over American musicians, as fans knew that if they purchased a particular single, they would not have to pay for it again on a subsequent album. In essence, the Beatles offered a product with a higher value proposition as compared to their American counterparts.
