One of my all time favorite songs on the White Album is “Dear Prudence”. I love the layering of vocals and instruments - I especially love the drum work on the last minute or so of the piece - I read somewhere that Paul played the drums on this song - don’t know if that’s true or not.
Lennon was on a talk show back in the day, and related that song was recorded in a single take, studio live.
It was just Lennon, McCartney and Harrison.
