Lennon's best ballad, McCartney's best rocker

In My Life/Twenty Flight Rock (or I Saw Her Standing There)

Because/ Back in the USSR.

These guys have a catalogue so big that it’s impossible to mention one song for each.

Paul tears up the vocals on “Oh, Darling” though. (And gets his Little Richard “Oooo!” in there as well.)

IMO you just opened and closed the thread in one swell foop. Agree 100% with both choices.

Not that it matters, LTS was recorded in ONE take, George Martin seeing no reason to waste time attempting to improve an almost perfect performance.

Band on the Run rocks for Paul

Imagine is John’s best ballad

Got a soft spot for Beautiful Boy.

Yes It Is/Paperback Writer

Oh. I’m very fond of Julia (John ballad) and Sgt. Pepper’s Lonely Hearts Club Band (Reprise) (Paul rocker).

But there are lots more. Maybe: Strawberry Fields (John ballad) and The End (Paul rocker).

Beatles:

In My Life / Got To Get You Into My Life

Post Beatles:

Hold On / Let Me Roll It.

Ooo, Julia, yeah!

“Julia” for Lennon
“Why Don’t We Do It In the Road?” by McCartney.

Interestingly, both are solo efforts.
