Which Beatles song has a French horn solo?

"For No One" is a song by the English rock band the Beatles from their 1966 album Revolver. It was written by Paul McCartney, and credited to Lennon–McCartney. An early example of baroque pop drawing on both baroque music and nineteenth-century art song, it describes the end of a romantic relationship. Mostly performed by the composer, the track is distinguished by its French horn line performed by Alan Civil, played first as a solo and then as counterpoint in the final verse. It was considered one of McCartney's most mature compositions to date on its release.
