We could not end D-A-B-F#-G-D-G-A without including the single most iconic interpretation of the song in the modern era. The song itself is an absolute masterpiece, as many Lennon/McCartney compositions were - but in this case, Paul got some help from Johann at the beginning.
McCartney accomplished this chord progression on piano at the beginning of the song in a unique way, however. His right hand was playing the chords. His left was playing single notes.
Lyrically, the song was imagined during some hard times Paul's parents were having. It's meant to be a comforting song - and the song nails that.
This particular version is what became the "Naked" version of the song, released in 2003. This was originally produced by George Martin.
Compare that to the original SINGLE version - not the album version. The SINGLE version - which was produced by Phil Spector. We didn't lose the Canon, but we did gain a Wall of Sound.
