Which of these songs is NOT in The Beatles' album "Sgt. Pepper's Lonely Hearts Club Band"?

The song "Strawberry Fields Forever" is not included in the Beatles album "Sgt. Pepper's Lonely Hearts Club Band" because it was released as a single prior to the album's release. The song was recorded during the same sessions for the album, but the band decided to release it as a separate single alongside another single, "Penny Lane." Therefore, "Strawberry Fields Forever" was not included in the album, even though it is highly regarded as one of the Beatles' most iconic and influential songs.
