the transcription I have of it (from "The Beatles Best' for piano-vocal-guitar) lists the chord differently.
we're in the key of F, and "far" is LH D, RH F, A, D, thus making Dmin. next the RH plays C for "a-" and "-way," which is notated Dm/C, although I can't say that I necessarily agree with that notation.
the Beatles often experimented with unconventional chords and chord progressions, and this song is one example of that. but it's a good one!
