Check out the last chord in this video & you'll see John & George on that Fadd9 chord & Paul on what still looks to me like a G. I do hear a D ringing though, so maybe he's on the 5th fret & 2nd string.

I'm spending way too much time on this.

Forgot to post the video link.

Of course, this being the 21st Century, there is transcription software to do the Fourier transform for you -- and do the conversion into musical language, too. Handy for those really quirky jazz transcriptions. For example, see:
