In 1989 or so I made an album of Solo Arrangements of Beatles' Tunes, A Beatles Collection. It included versions of more than 20 songs. This is the first one that I have revisited and done a more formal arrangement of.
I really think it is important to know the lyrics and try to play the melody like you're singing the song. This lesson covers 3 verses, all slightly different, and the chorus. Some experience with alternate bass fingerpicking is definitely required here but it is not too difficult, unless you want to play it at the Beatles speed, which I do not recommend.
This is the type of piece that encourages a bit of improvisation as well and does not need to be played note-for-note the same every time. It would even be fine to just learn the first verse and the chorus, without the embellishments that are done in the other verses.
